Question

One heterozygous purple-flowering pea plant is crossed with a white flower. If purple is dominant over white, what are the expected phenotypic results?

A) 25% purple, 75% white
B) 100% purple
C) 50% purple, 50% white
D) 75% purple, 25% white

Answer 1

Explanation:

Heterozygous Purple flower - Pp

Gametes : P and p

Recessive white flower: pp

Gametes: p

Fusion thus yields: Pp (Purple) and pp (white)

The ratio is 1:1

Hence, it is 50% purple and 50% white.
