Question

which of the following statements correctly describes a monohybrid cross?
a monohybrid cross involves organisms that are heterozygous for one character.
a monohybrid cross involves a single parent.
a monohybrid cross produces a single offspring.
a monohybrid cross is performed for one generation.

Explanation:

A monohybrid cross is a genetic cross that involves organisms which are heterozygous for one character. For example, in Mendel's experiments with pea plants, when he crossed plants that were heterozygous for seed color (Yy x Yy, where Y represents the dominant allele for yellow seeds and y represents the recessive allele for green seeds), it was a monohybrid cross. A monohybrid cross is not performed for just one generation (it can be repeated over multiple generations to study inheritance patterns), it does not produce a single offspring (it produces multiple offspring in a generation for analysis), and it involves two parents (not a single parent as sexual reproduction in most cases, which is relevant for monohybrid crosses in diploid organisms, involves two parents contributing gametes).

Answer:

A monohybrid cross involves organisms that are heterozygous for one character.
