Question

1. A sample of 300 adults from California were genotyped for Gene F. The following are the number of genotypes in this sample:

102 FF           174 Ff            24 ff

Based on the allele frequencies of this sample, what is the predicted frequency of the heterozygous genotype for the entire population in the state of California?

A) 0.47

B) 0.37

C) 0.16

D) 0.58

E) 0.5

2.

A sample of 300 adults from California were genotyped for Gene F. The following are the number of genotypes in this sample:

102 FF           174 Ff            24 ff

Based on the allele frequencies of this sample, what is the predicted frequency of the homozygous dominant genotype for the entire population in the state of California?

A) 0.48

B) 0.16

C) 0.63

D) 0.34

E) 0.4

3. A sample of 300 adults from California were genotyped for Gene F. The following are the number of genotypes in this sample:

102 FF           174 Ff            24 ff

True or False: 30 years from now, the dominant allele frequency for Gene F is 0.70. The population is in Hardy-Weinberg Equilibrium for Gene F.

Answer 1

Genotype frequency in a population is the number of individuals with a given genotype divided by the total number of individuals in the population.

No of Heterozygous genotype (Ff) = 174

Total number of individual in the population = 300

Hence, Frequency of heterozygous genotype =   

No: offf Totalno : ofindividual inpopulation

= $\frac{174}{300}$ = 0.58

This result tells us that the allele frequency of Ff is 0.58 .

Answer is option D= 0.58
