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:
True
Explanation:
The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.

Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.
