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
