Genetics: Understanding Monohybrid and Dihybrid Crosses

What is the difference between a monohybrid cross and a dihybrid cross in genetics?

True False

Answer:

The statement "a monohybrid cross involve two genes" is false. A monohybrid cross involves only one gene.

Monohybrid cross refers to a breeding experiment that involves only one trait or one gene. For instance, if two parents were heterozygous for flower color, such as pink (Pp), they can be crossed to produce offspring with different variations of the trait. In this case, there's only one gene (P) that's responsible for flower color.

The other allele (p) is a recessive allele that doesn't affect the flower color when present in a heterozygous state. A dihybrid cross, on the other hand, involves two different genes.
