Question

If alleles of the two genes assort independently, what is the predicted ratio of parental:recombinant types from cross (iii)?

A. 3:1
B. 1:3
C. 4:0
D. 0:4
E. 2:2

Answer 1

Option E , 2:2

Step-by-step explanation:

As per Mendel's theory of independent assortment, alleles for two or more different traits are expressed independently which means expression of one allele is not affected by presence of unaffected allele.

Recombination types of offspring are those which have genetic structure different from their parents.

In the cross (iii), the number of parental genetic combination is equal to the number of recombination types.

Hence, the ration of parental and offspring genetic combination is 2:2

Option E is correct
