Question
Grain colour in wheat is determined by three paris of polygene. Following the cross AABBCC(DARK COLOUR) × aabbcc (light colour in F2 generation ehat proportion of the progeny is likely is to resemble either parent?
Options
A.Half
B.less than 5 percent
C.One third
D.None of these
Solution
The F2 generation will show the intermediate colour because of quantitative inheritence. In case of crossing between AABBCC(dark colour ) and aa bb cc (light colour ), in F2 generation seven phenotypes will be obtained with ratio 1 : 6 : 15 : 20 : 15 : 6 : 1. The total number of which omly teo will be likely resemble with either parents. hence, their percentage in F2 generation would be 3.12. i.e. less than 5%.
