The genotypic ratio of Mendel’s monohybrid cross is A. 2:2 B. 1:1:1:1 C. 3:1 D. 1:2:1
Option D Out of the four types of individuals of the F2 progeny- one is homozygous dominant (TT), two are heterozygous dominant (Tt) and one is homozygous recessive (tt). Thus the F2 genotypic ratio of Mendel's monohybrid cross is 1:2:1.
