## FAQs

**How do you find the dominant allele frequency?** The dominant allele frequency (p) can be calculated using the formula: p = (number of dominant alleles) / (total number of alleles).

**How do you find the allele frequency of a homozygous dominant?** In a homozygous dominant individual, both alleles are the same and are dominant. Therefore, the allele frequency of the homozygous dominant allele is equal to the frequency of the dominant allele in the population.

**How do you calculate allele frequency in autosomal recessive?** For autosomal recessive traits, you can calculate the frequency of the recessive allele (q) using the formula: q = √(frequency of recessive individuals).

**Do dominant alleles have higher frequency?** Not necessarily. Dominant alleles can have either higher or lower frequencies depending on the specific population and trait being studied.

**What is the frequency of the dominant allele is 60?** If the frequency of the dominant allele (p) is 60%, then the frequency of the recessive allele (q) would be 1 – p = 40%.

**How do you calculate P and Q in Hardy-Weinberg?** In the Hardy-Weinberg equation, p^2 + 2pq + q^2 = 1, p represents the frequency of the dominant allele, and q represents the frequency of the recessive allele.

**How to calculate the frequency of a genotype from allele frequency?** In a population in Hardy-Weinberg equilibrium, you can calculate the frequency of a specific genotype using the formula: genotype frequency = p^2 (for homozygous dominant) + 2pq (for heterozygous) + q^2 (for homozygous recessive).

**What is the frequency of homozygous dominant individuals in the population?** The frequency of homozygous dominant individuals (AA) is represented by p^2.

**What is the formula for the frequency of homozygous recessive genotype?** The frequency of homozygous recessive individuals (aa) is represented by q^2.

**How do you find the percentage of homozygous dominant?** To find the percentage of homozygous dominant individuals, calculate p^2 and then multiply it by 100.

**How do you find the frequency of allele genotype and phenotype?** Allele frequency is calculated using the allele counts, genotype frequency involves using the Hardy-Weinberg equation, and phenotype frequency can be calculated from genotype frequency if the phenotype is directly related to the genotype.

**What are the frequencies of the dominant and recessive alleles?** In a population in Hardy-Weinberg equilibrium, p represents the frequency of the dominant allele, and q represents the frequency of the recessive allele.

**Are dominant alleles found at greater frequency than recessive alleles in populations?** Not necessarily. Dominant alleles can have higher, lower, or similar frequencies compared to recessive alleles in populations.

**What is the frequency of an allele in a population is 100?** An allele frequency cannot be 100% in a population, as that would imply that there are no other alleles for that gene in the population.

**What if the frequency of the dominant phenotype is 75?** If the frequency of the dominant phenotype is 75%, you would need more information about the population’s genetic makeup to calculate allele frequencies.

**When a certain trait allele frequency is 100?** If the frequency of a certain trait allele is 100%, it means that every individual in the population carries that allele and no individuals have the alternative allele.

**What is the Hardy-Weinberg symbol for the frequency of the dominant allele?** The symbol for the frequency of the dominant allele is usually represented as “p.”

**What is the correct formula for the Hardy-Weinberg equation?** The correct formula for the Hardy-Weinberg equation is: p^2 + 2pq + q^2 = 1.

**What does 2pq mean in Hardy-Weinberg equilibrium?** In the Hardy-Weinberg equation, 2pq represents the frequency of heterozygous individuals (Aa) in the population.

**Is genotype frequency the same as allele frequency?** No, genotype frequency refers to the proportion of individuals with a specific genotype, while allele frequency refers to the proportion of a specific allele in the population.

**How do I calculate frequency?** Frequency is calculated by dividing the number of occurrences of a specific event by the total number of events.

**What is the allele frequency of genotypes?** Allele frequency of genotypes can be calculated using the Hardy-Weinberg equation: p^2 + 2pq + q^2 = 1.

**How do you calculate the frequency of a gene and genotype?** Gene frequency is calculated by adding up the frequencies of all alleles for that gene in the population. Genotype frequency is calculated based on the Hardy-Weinberg equation for homozygous and heterozygous genotypes.

**What is the dominant frequency?** Dominant frequency could refer to the frequency of the dominant allele in a population.

**What is the frequency of a recessive allele in a population that is in Hardy Weinberg equilibrium?** In a population in Hardy-Weinberg equilibrium, the frequency of a recessive allele (q) can be calculated using the formula: q = √(frequency of recessive individuals).

**What is the formula for heterozygous dominant?** The frequency of heterozygous dominant individuals (Aa) can be calculated using the formula: 2pq.

**What is the ratio of homozygous dominant to heterozygous recessive?** The ratio of homozygous dominant (AA) to heterozygous recessive (Aa) depends on the allele frequencies in the population and can be calculated using the formula: p^2 : 2pq.

**What is the proportion of homozygous dominant and homozygous recessive?** The proportion of homozygous dominant (AA) individuals is represented by p^2, and the proportion of homozygous recessive (aa) individuals is represented by q^2.

**What is the ratio from dominant to recessive?** The ratio from dominant to recessive alleles depends on the allele frequencies in the population and can be expressed as p : q.

**What is the formula for minor allele frequency?** Minor allele frequency (MAF) is calculated by dividing the number of minor alleles by the total number of alleles.

**How do you find the dominant phenotype?** The dominant phenotype is expressed in individuals who have at least one copy of the dominant allele. It’s observed when the dominant allele masks the effects of the recessive allele.

**How is gene frequency connected with whether a gene is dominant or recessive?** Gene frequency is the proportion of a specific allele in a population. Whether a gene is dominant or recessive determines how the phenotype is expressed in heterozygous individuals.

**Are dominant traits always at a higher frequency than recessive traits?** No, dominant traits are not always at a higher frequency than recessive traits. The frequency of a trait depends on various factors, including selective pressures and population genetics.

**How do you calculate change in allele frequency?** The change in allele frequency can be calculated by subtracting the initial allele frequency from the final allele frequency.

**How is allele frequency related to population size?** Allele frequency is affected by population size, genetic drift, and selection pressures. Smaller populations are more susceptible to allele frequency changes due to random events.

**How many alleles are in a population of 100?** If considering a single bi-allelic gene, a population of 100 diploid individuals would have 200 alleles in total (2 alleles per individual).

**What does a gene frequency of 50% indicate?** A gene frequency of 50% indicates that both alleles for that gene are present in equal proportions in the population.

**What if 72 out of 200 individuals express the recessive phenotype?** If 72 out of 200 individuals express the recessive phenotype, you can calculate the frequency of the recessive allele using q = √(recessive phenotype frequency).

**When 75% of the offspring show the dominant character?** If 75% of the offspring show the dominant character, you can calculate the frequency of the dominant allele using p = √(dominant phenotype frequency).

**What does an allele frequency of 0.5 mean?** An allele frequency of 0.5 (50%) means that the allele is present in half of the population’s alleles.

**What is the maximum allele frequency?** The maximum allele frequency is 1.0 (100%), which would indicate that all individuals in the population have that allele.

**Can allele frequencies be greater than 1?** No, allele frequencies cannot be greater than 1, as they represent proportions of alleles in a population.

**How do you calculate the allele frequency of a homozygous dominant?** The allele frequency of a homozygous dominant allele (AA) is equal to the frequency of the dominant allele in the population.

**How do you find the allele frequency of three alleles?** When dealing with three alleles, you would need to consider the frequencies of each individual allele and their interactions in the population.

**How do you find allele frequencies P and Q?** Allele frequencies P (dominant) and Q (recessive) can be calculated using p + q = 1, where p represents the frequency of the dominant allele and q represents the frequency of the recessive allele.

**What are the two equations for Hardy-Weinberg calculations?** The two equations for Hardy-Weinberg calculations are: p^2 + 2pq + q^2 = 1 and p + q = 1.

**What are the two equations for Hardy-Weinberg equilibrium?** The two equations for Hardy-Weinberg equilibrium are: p^2 + 2pq + q^2 = 1 (genotype frequencies) and p + q = 1 (allele frequencies).

**How to calculate if a population is in Hardy-Weinberg equilibrium?** To determine if a population is in Hardy-Weinberg equilibrium, compare the observed genotype frequencies with the expected frequencies calculated using the Hardy-Weinberg equation.
