Question

in pea plants, purple flowers (p) are dominant over white flowers (p). if two heterozygous purple-flowered plants are crossed with each other, then what are the possible genotypes of the offspring?
a pp only
b pp and pp
c pp and pp
d pp, pp and pp

Explanation:

Step1: Identify parent genotypes

Both parents are heterozygous: $Pp$

Step2: Set up Punnett square

	$P$	$p$
$p$	$Pp$	$pp$

Step3: List unique genotypes

Extract distinct genotypes from the square: $PP$, $Pp$, $pp$

Answer:

D. Pp, PP and pp
