Question

in f2 generation the phenotype ratio 9:3::3:1 state the rule of inheritance of traits as observed by mendal​

Answer 1

Answer:

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

Answer 2

Explanation:

Independent Assortment of genes
