Question

Quizplus · Accepted Answer

A monohybrid cross involves breeding two individuals that differ in only one trait, such as flower color or seed shape. This allows the inheritance of that trait to be studied in their offspring. Option A is incorrect because the second generation of a self-fertilized plant is known as the F2 generation, which is not necessarily a monohybrid cross. Option B is incorrect because it does not specify which trait the parental varieties have in common. Option D is incorrect because it implies that only one trait is present in the parental varieties, which is not necessarily the case in a monohybrid cross.
