Question

the ratio obtained is 9: 3: 3: 1 in which perental as well as new combinations are observed. This indicates that progeny plants have not inherited a single whole gene set from each parent . Every germ cell takes one chromosome from the pair of maternal and paternal chromosomes when two germ cells combine 1 pair of characters is independent of the Other pair of character​

Answer 1

Answer:

independent assortment of gene

Explanation:

A cross is made between the two parents based on two pairs of contrasting characters is called Dihybrid cross. A cross is made between homozygous yellow round seeds(YYRR) to another homozygous green wrinkled seeds(yyrr). In the F1 generation, all plants are heterozygous yellow round(YyrRr). When this plant is subjected to self pollination, in the F2 generation, 9 plants are Yellow round, 3 plants are yellow wrinkled, 3 plants are green round and 1 plant is green wrinkled are formed. This called Dihybrid phenotypic ratio 9:3:3:1. Mendel is expressed this one as Law of independent assortment’.

So, the correct option is ‘Independent assortment of genes’.
