Give reasons for the appearance of new combinations of characters in the F2 progeny.
F1 generation of the plant contain round and yellow seeds and by crossing the gametes formed by the f1 generation gives the new combination in the f2 generation i.e, Round yellow, Round green, Wrinkled yellow, wrinkled green with 9:3:3:1 ratio.
This depicts the law of independent assortment in which alleles of different characters located in the different pairs of homologous chromosomes are independent of one another in their segregation during the gamete formation and in the offspring by the fertilization, both processes will occur randomly. As in the above paragraph this shows that each pair of allele is independent of one another. This shows that chances of seed to be round or wrinkled does not depend on their chances to be yellow or green.
