How can a pure white mouse help determine the genotype of a black mouse? (Hint: We cannot see genotype but we can see difference

sattari [20]

Answer:

A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.

Explanation:

If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.

Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determin

vova2212 [387]

Answer:

See the answer below

Explanation:

Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).

Heterozygous long leg, weak muscle = Llgg

Heterozygous long leg, strong muscle = LlGg

Llgg x LlGg

Offspring:

2 LLGg - Long leg, strong muscle

4 LlGg - Long leg, strong muscle

2 LLgg - Long leg, weak muscle

4 Llgg - long leg, weak muscle

2 llGg - short leg, strong muscle

2 llgg - short leg, weak muscle

Ratio of offspring with long leg and strong muscle = 6/16 or 3/8

Ratio of offspring with long leg and weak muscle = 6/16 or 3/8

Ratio of offspring with short leg and strong muscle = 2/16 or 1/8

Ratio of offspring with short leg and weak muscle = 2/16 or 1/8
