A) Half
B) Less than 5 percent
C) One third
D) None of these
Correct Answer: B
Solution :
Polygene results in quantitative inheritance which is characterised by occurrence of intermediate forms between the parental type. In case of crossing between AABBCC (dark colour) and aabbcc (light colour) in \[{{F}_{2}}\] generation seven phenotypes will obtain with ratio of 1: 6 : 15 : 20 : 15 : 6 : 1. The total number of progeny is 64, out of which only two will be likely resemble with either parents. Hence, their proportion in \[{{F}_{2}}\] generation would be 3.12 i.e., less than 5%.You need to login to perform this action.
