Question

A tall pea plant with genotype DD can produce what type of gametes?

(a) only D
(b) only d
(c) 50% D, 50% d
(d) 75% D, 25% d
(e) 25% D, 75% d

Answer 1

A tall pea plant with genotype DD can only produce gametes with D alleles.

Step-by-step explanation:

A tall pea plant with genotype DD can only produce gametes with D alleles. This is because a tall pea plant with genotype DD is homozygous dominant, meaning it has two copies of the dominant D allele.

Therefore, all of its gametes will contain the D allele.
