How to Calculate the Frequency of the ‘b’ Allele from Genotype Data in a Population
In a sample from a population there were 65 individuals with BB genotype, 30 individuals with Bb genotype and 15 individuals with bb genotype. The frequency of the ‘b’ allele […]

How to Calculate Allele Frequencies from Homozygote Frequency in Hardy-Weinberg Equilibrium
The frequency of homozygotes in a diploid population is 0.68. Assuming that the population is in Hardy- Weinberg equilibrium, the frequencies of the two alleles are (1) 0.1 and 0.9 […]

How to Calculate the Percentage of Homozygous Dominant Individuals Using Hardy-Weinberg Equilibrium
In a population that is in Hardy-Weinberg equilibrium, the frequency of the recessive homozygote genotype of trait q is 0.04. The percentage of individuals homozygous for the dominant allele is […]

How to Calculate the Expected Number of Heterozygotes in a Hardy-Weinberg Population Sample
The frequencies of alleles ‘A’ and ‘a’ in a population at Hardy- Weinberg equilibrium are 0.7 and 0.3, respectively. In a random sample of 250 individuals taken from the population, […]

How to Calculate the Number of Heterozygotes in a Hardy-Weinberg Population Sample
In a population, alleles p and q are known to be in a ratio of 0.7p: 0.3q. At Hardy- Weinberg equilibrium how many heterozygotes (pq) can be expected in a […]

Calculating Genotype Numbers in a Hardy-Weinberg Population: Red, Pink, and White Flowered Plants
In a population that is in a Hardy-Weinberg equilibrium, 40% of the plants are recessive homozygotes and produce white flowers (WF). If the total number of individuals in the population […]

How to Calculate the Frequency of Heterozygotes for Red Hair Using Hardy-Weinberg Equilibrium
Red hair is a recessive trait in human. In a randomly mating population in Hardy-Weinberg equilibrium approximately 9% of individuals are red- haired. What is the frequency of the heterozygotes? […]
