Question

when mendel crossed purebred purple flowering plants (pp) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring?
25 percent white and 75 percent purple
50 percent white and 50 percent purple
100 percent purple
100 percent white

Explanation:

This is a classic Mendelian genetics problem. Purebred purple plants have a homozygous dominant genotype (PP), and purebred white plants have a homozygous recessive genotype (pp). When crossed, all offspring inherit one dominant P allele from the purple parent and one recessive p allele from the white parent, resulting in a heterozygous (Pp) genotype. The dominant P allele expresses the purple flower trait, so all offspring will have purple flowers.

Answer:

100 percent purple
