D) AB, ab, Ab and aB.
Correct Answer: A
Solution :
: In normal conditions there are chances of crossing over and four types of gametes are formed. These gametes show linkage in 50% of the gametes and 50% of the gametes are of recombination type. Because crossing over occurs in between the two non-sister chromatids of a homologous chromosome pair only and the other two chromatids are not involved. If there is no crossing over then, only two types of gametes will be formed. So, the parental combination would be AB and ab as \[1:1\] in the absence of recombination.You need to login to perform this action.
