in pea plants, purple flowers (p) are dominant over white flowers (p). Show the cross between two heterozygous plants
Ostrovityanka [42]

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

I hope this was the answer you were looking for!
