Zoology - Principles of Inheritance and Variation Question with Solution | TestHub
In a cross inDrosophila, the heterozygous member with grey body (b+) and long wings (vg+) was crossed with black body and vestigial wings, the progeny had the following ratio grey vestigial 24: grey long 126: black long 26: black vestigial 124. What is the frequency of recombinants in the population?

Solution:
In a cross inDrosophila, the heterozygous member with grey body (b+) and long wings (vg+) was crossed with black body and vestigial wings, the progeny had the following ratio grey vestigial 24: grey long 126: black long 26: black vestigial 124.
P1= grey and long
P2= black and vestigial
Their recombination results in grey vestigial and black long variants.
Total population: 300
Recombinant population (26 grey vestigeal + 24 black long): 50
Frequency of recombinants in the population: 50/300 * 100 = 16.7 %
