Question

1. A short female with red flowers is crossed with a tall male plant with white flowers. Both shortness and white flowers are recessive traits. What are all of the height and color combinations with the offspring?

2. A women has A antigens in her blood, her husband has the blood genotype BO. What are all the possible genotypes of their children?

Answer 1

When a short female pea plant with red flowers is crossed with a tall male pea plant with white flowers, the possible height and color combinations of their offspring are tall with red flowers, tall with white flowers, and short with red flowers.

Step-by-step explanation:

When a short female pea plant with red flowers is crossed with a tall male pea plant with white flowers, we can determine the height and color combinations of their offspring using a Punnett square. The shortness trait and white flower trait are both recessive, meaning they are only expressed when an individual has two copies of the recessive allele. Here are the possible height and color combinations:

Tall with red flowers

Tall with white flowers

Short with red flowers
