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: ![\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D)
rough white: ![\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D)
smooth black: ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
smooth white: ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
Hope that answers the question, have a great day!
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
Using "global positioning", I believe.
It’s FALSE! Some people do not live off of that, that’s why they’re vegans! So FALSES
