Question

Calculating expected genotypic frequencies and individuals in a population from allele frequencies:

3.1 In a population of peas, the frequency of the dominant allele for a purple flower is 0.77 and the frequency of the recessive allele for a white flower is 0.23. What would the genotypic frequencies be if the population is in equilibrium?

_____   = Frequency of homozygous dominant individuals

_____   = Frequency of heterozygous individuals

_____   = Frequency of homozygous recessive individuals

How many individuals would you expect of each genotype in a population of 400 peas?

_____   = Number of homozygous dominant individuals

_____   = Number of heterozygous individuals

_____   = Number of homozygous recessive individuals

3.2 In mice, a mahogany coat color allele is dominant over the tan coat color allele. In a population of mice, the frequency of the allele for mahogany coat color is 0.49 and the frequency of the allele for tan coat color is 0.51. What would the genotypic frequencies be if the population is in equilibrium?

_____   = Frequency of homozygous dominant individuals

_____   = Frequency of heterozygous individuals

_____   = Frequency of homozygous recessive individuals

How many individuals would you expect of each genotype in a population of 120 mice?

_____   = Number of homozygous dominant individuals

_____   = Number of heterozygous individuals

_____   = Number of homozygous recessive individuals

3.3 In humans, the free earlobe allele is dominant over the attached ear lobe allele. In a population of humans, the frequency of the allele for free earlobes is 0.35 and the frequency of the allele for attached earlobes is 0.65. What would the genotypic frequencies be if the population is in equilibrium?

_____   = Frequency of homozygous dominant individuals

_____   = Frequency of heterozygous individuals

_____   = Frequency of homozygous recessive individuals

How many individuals would you expect of each genotype in a population of 40 humans?

_____   = Number of homozygous dominant individuals

_____   = Number of heterozygous individuals

_____   = Number of homozygous recessive individuals

3.4 In a population of peas, the frequency of the dominant allele for a yellow seed is 0.33 and the frequency of the recessive allele for a green seed is 0.67. What would the genotypic frequencies be if the population is in equilibrium?

_____   = Frequency of homozygous dominant individuals

_____   = Frequency of heterozygous individuals

_____   = Frequency of homozygous recessive individuals

How many individuals would you expect of each genotype in a population of 200 peas?

_____   = Number of homozygous dominant individuals

_____   = Number of heterozygous individuals

_____   = Number of homozygous recessive individuals

3.5 In humans, the widow’s peak allele is dominant over the straight hairline allele. In a population of humans, the frequency of the allele for a widow’s peak is 0.77 and the frequency of the allele for a straight hairline is 0.23. What would the genotypic frequencies be if the population is in equilibrium?

_____   = Frequency of homozygous dominant individuals

_____   = Frequency of heterozygous individuals

_____   = Frequency of homozygous recessive individuals
