◆ Dihybrid cross by Mendel:

◆ Mendel crossed pure bred pea plant having round yellow seeds with pure needles plant having wrinkled green seeds.

◆ He observed that only round yellow seeds were produced in the first filial generation.When he crossed round yellow seeds by self pollination four new types of seeds were produced.

◆ Round yellow , Wrinkled green , Round green, Wrinkled yellow.From this he concluded that two pair of orignal characteristics combined in first filial generation and behaved independently in subsequent stages.❤️

◆ Law of Independent Assortment :✔️✔️

Allel pair separate or segregate during gamete formation.This means that traits are transmitted to offsprings independently.

◆Phenotypic ratio ----- 9:3:3:1
