Mendel crossed purebred purple-flowered plants with purebred white-flowered plants, and all of the resulting offspring produced purple flowers. The offspring are all ________, and the allele for purple flowers is ________.

Respuesta :

Answer:

Heterozygous and dominant

Explanation:

When Mendel performed the purebred purple flower with the purebred white flower he found that the purple flowers were obtained.

Suppose,

the genotype of the purple flower is- PP (purebred)

the genotype of white flower- pp ( purebred)

crossing them we obtain

                         PP      x     pp

                            P          P

                 p       Pp        Pp

                p       Pp        Pp

We see that all the offspring obtained are heterozygous (Pp) and are purple colored.

This shows that the allele for the purple flower is dominant.

Thus, heterozygous and dominant is correct.
