Answer:
<em>P p</em>
<em>P</em> PP Pp
<em>p </em>Pp pp
PP=Homozygous purple
Pp= heterozygous purple
pp=homozygous White
Explanation:
I tried to type out the cross. The bold letters are the heterozygous plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.
heterozygous= Pp
Homozygous= PP or pp
