77.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 In the F2 generation of a typical monohybrid cross, we get homozygous and heterozygous combinations. These combinations appear in the following ratio 1(homozygous dominant): 2(heterozygotes):1 (homozygous recessive). Thus the genotypic ratio of a monohybrid cross is 1:2:1
