Question

Explain monohybrid and dihybrid test cross.

Hint:

Remember: Monohybrid – one trait; Dihybrid – two traits; both determine genotype.

Answer 1

A monohybrid test cross studies a single trait, while a dihybrid test cross examines two traits simultaneously.A monohybrid test cross involves crossing an individual showing a dominant phenotype with a homozygous recessive to determine the genotype.
A dihybrid test cross assesses inheritance of two traits simultaneously.
