Dangling high above the ground, this rock climber relies on muscular strength to pull her weight higher and higher. However, mus
cles alone will not ensure her safety.
Explain why the muscular system cannot act alone to perform a skill such as rock climbing. Describe what other systems must be a part of this rock climber's game plan.

Answer:
Yes, they would be able to produce weak muscled guinea pigs
Please see details below
Explanation:
This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.
According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:
GG - G and G
RR - R and R
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
GR, GR, GR, and GR
This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.
