Answer:
the genotype of the parent guinea pigs are as follows:
RrBb (rough, black) and Rrbb (rough, white)
Explanation:
Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.
After making the dihybdrid cross, the probability obtained for each phenotype is given below:
rough black: 
rough white: 
smooth black: 
smooth white: 
Hope that answers the question, have a great day!
Rachel is a frail and fragile girl who is prone to injury and bruising William Sheldon would most likely have classified her body as a ectomorph.
William classified people according to their body into three types:
1. Endomorphs- rounded and soft, with comfortable and extroverted personality,
2. Mesomorphs-square and muscular, with dynamic and aggressive personality,
3. Ectomorphs-thin and fine-boned with introverted, and sensitive personality.
The answer is A or C cuz it the stomach has more part to break down foods.
The chromosomes would not be duplicated and meiosis would not be able to be completed after meiosis 1 (meiosis 1 could still occur as the gametes go from diploid to haploid).
