Mendel's law of independent assortment can be demonstrated by
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’.
