When Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), what were the flower colors
zavuch27 [327]
The answer is <span>100 percent purple
</span>
Let P be dominant allele for purple flowers and p recessive allele for white flowers. So purebred purple flower has two P alleles and its genotype is PP and purebread white flower has two p alleles and its genotype is pp. Since P is dominant over p, when found together like in heterozygous plants (Pp), the flowers will express dominant allele and will be purple.
So, a cross between <span>purebred purple flowering plants (PP) with purebred white flowering plants (pp) will have 100% of the offspring with genotype Pp and purple flower color.
</span>
Parents:               PP      x       pp
Offspring:        Pp     Pp      Pp    Pp
