Question

Mendel crossed plants bearing red flowers (RR) with the plants bearing white flowers (rr) and produced progeny from them. The plants with red flowers obtained in F₁ generation were different from the plants with red flowers of the parental generation. Why? Explain with reasons.

Accepted Answer

Mendel performed crosses, which involved mating two true-breeding individuals that have different traits. A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. A recessive trait is a trait that is expressed when an organism has two recessive alleles.

In parent generation, plant bearing red flowers has both the dominant traits RR. In parent generation, plant bearing white flowers has both the recessive traits rr.

F1 generation plant inherits one copy of dominant trait (red) and one copy of recessive trait (white) from the parental plants Rr. But only the dominant trait (red) is expressed.
