Question

a white flowered plant is crossed with a plant that is heterozygous for the trait. what percent of the offspring will have purple flowers?

Answer 1

Answer:

Punnet square can be described as a diagram which is used to check the probability of offsprings produced by crossing over of parents.

If a homozygous white plant is crossed with a heterozygous white plant, then none of the F1 offsprings will not have purple flowers. Considering white-flowered plant to be dominant for the trait.

If a heterozygous white plant is crossed with a heterozygous white plant, then about 25% of the F1 plants will have purple flowers. Considering white trait to be dominant.
