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:

Step1: Determine parental genotypes

Pure - bred purple is PP and pure - bred white is pp.

Step2: Set up Punnett - square cross

When PP is crossed with pp, all gametes from PP are P and all gametes from pp are p. The cross is P×p.

Step3: Analyze offspring genotypes

All offspring will have the genotype Pp. Since the purple allele (P) is dominant over the white allele (p), all offspring will have purple flowers.

Answer:

100 percent purple
