Genetics: monohybrid cross MCQ - Practice Questions with Answers
Solve 1 Genetics: monohybrid cross questions for RAS/RPSC preparation.
Practice questions
Q1How many types of genotypes are formed in the F2 generation of a monohybrid cross?
Explanation
In a monohybrid cross between two heterozygous parents, the F2 generation shows three genotypic forms: homozygous dominant, heterozygous, and homozygous recessive. Their usual genotypic ratio is 1:2:1. Four would refer to the total boxes in a simple Punnett square, not the number of distinct genotypes. Two ignores the heterozygous form. Nine is associated with the number of genotypes in the F2 generation of a dihybrid cross, not a monohybrid cross.
