Question

Mom's genotype is Hh, and Dad's hair isn't brown. Brown hair is dominant to red hair. Use the letter h for hair. What are the probabilities and ratio for their offspring?

a. 3:1, 75% brown hair, 25% red hair
b. 1:2:1, 25% brown hair, 50% carrier, 25% red hair
c. 1:1, 50% brown hair, 50% red hair
d. 4:0, 100% brown hair, 0% red hair

Answer 1

The phenotypic ratio of the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous) is 1 tall : 1 dwarf.

Step-by-step explanation:

The phenotypic ratio of the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous) can be predicted using a Punnett square. In this case, the phenotypic ratio of the offspring would be 1 tall : 1 dwarf.
