Question

Now it is time to do some word problems! In pea plants purple flower color is dominant over white flower color. A pea plant that is homozygous purple-flowered is crossed with a pea plant that is white-flowered. Which answer fits the predicted phenotype(s) of their offspring with respect to flower color?

Answer 1

Answer:

All the offsprings would be heterozygous purple colored flower

Explanation:

Given

Purple color flower is dominant over white color flower

Let the allele for purple color of flower be represented by "P"

and the allele for white color flower be represented by "p"

A pea plant that is homozygous purple-flowered is crossed with a pea plant that is white-flowered.

Genotype of homozygous purple-flower is "PP"

and Genotype of homozygous white-flower is "pp"

Cross between PP and pp produce the following offspring

PP * pp

Pp, Pp , Pp , Pp

All the offsprings would be heterozygous purple colored flower
