In fruit flies, vestigial wings (v) are recessive to normal wings (V). In a breeding study, 6,000 flies homozygous for vestigial wings mate at random with 4,000 flies homozygous for the normal allele.
a. What is the frequency of each genotype in the F1 generation?
b. What would the proportion of phenotypes be?
c. What is the frequency of the two alleles, V and v, in the F1 generation?

These ideas are examined.

Solution Summary

In fruit flies, vestigial wings are recessive to normal wings . Through a breeding experiment we can calculate:-
a. the frequency of each genotype in the F1 generation
b. the proportion of phenotypes
c. the frequency of the two alleles in the F1 generation

Solution Preview

Total number of fruit flies = 6000 + 4000 = 10,000

Hence, frequency of recessive gene 'v' = 6000/10000 = 0.6
Frequency for dominant gene 'V' = 4000/10000 = 0.4

Here, p = 0.4 and q = ...
