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!

Answer:
AWWWW thats sad i get it but dont know it
Explanation:
Bones, muscles are connected to the bones, and supports the entire body
Let's suppose that "long" is the dominant allele and "oval" is the recessive allele.
let's suppose also that red + white genotype give a pink phenotype
every radish has 2 genotypes for each gene, one from the mother and one from the father
The proportions are: if the radish are homozygotes
red red; long long x white <span>white ;</span> oval oval
red white oval long ; red white oval long ; red white oval long ; red white oval long
We will have 100% of pink - long radish.
A crossmatch from homozygotes species give always a unique phenotype
