Question

HELP!!! MAJOR GRADE!!!!!

Gregor Mendel conducted thousands of genetic experiments using pea plants. Mendel is called the Father of Genetics because it was these studies that lead to the principles of genetics. In one of his many experiments, he crossed purple-flowered pea plants with white-flowered pea plants. Much to his surprise, all of the offspring turned out to be peas with purple flowers in appearance.

Although Mendel used the term factors instead of genes, how did Mendel explain why all the pea plants had purple flowers and not a mixture of white and purple flowers?

A.The offspring received the factors (genes) from both parents, but the genotype for purple flowers dominated over white flower pea plants.

B.The offspring only received the factors (genes) from the parent with the genotype for purple flowers and nothing from the white flower parent.

C.The offspring received the factors (genes) from both parents, but the phenotype for purple flowers dominated over the factor for white flowers.

D. The offspring only received the factors (genes) from the parent with the phenotype for purple flowers and nothing from the white flower parent.

Answer 1

A

Step-by-step explanation:

The purple gene was dominant, so though the plants got "factors" from both parents, only the purple gene was expressed in their phenotype (purple petals).
