. Give reasons for the appearance of new combinations of characters in the F2 progeny.


Best Answer

Answer: F1 plants have round and yellow seeds. Cross between generations can give rise to new combinations in F2 generation with round-yellow, round green, wrinkled yellow and wrinkled green in the ratio of 9 : 3 : 3: 1.

This shows that the chances for the pea seed to be round or wrinkled do not depend on their chances to be yellow or green. Hence each pair of alleles is independent of the other pair. This is called an independent assortment.
