Question

Mendel's law of independent assortment can be demonstrated by

• A. Test cross
• B. Back cross
• C. Monohybrid cross
• D. Dihybrid cross

Answer 1

The correct option is D Dihybrid cross

A.Test cross – crossing of F₁ individual with homozygous recessive progeny is called Test cross. It is used to determine whether F₁ progeny is homozygous or heterozygous.

B.Back cross – Crossing F₁ progeny with any one of the parents.

C.Monohybrid cross – Cross is made between a homozygous dominant parent to another homozygous recessive parent on the basis of one character. By using this cross Mendel postulated Law of dominance and Law of Segregation.

D.Dihybrid cross – Cross is made between a homozygous dominant parent to another homozygous recessive parent on the basis of twocharacters. By using this cross Mendel postulated Law of Independent assortment.

So, the correct option is ‘Dihybrid cross’.
