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!
The answer is Clean Water Act
Answer:
Explanation:
RNA is single stranded While DNA is double stranded
RNA contains uracil while DNA contains thymine
RNA as the sugar ribose while DNA has the sugar deoxyribose
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome. Key Takeaways: Chromosome Mutations
Complete question:
In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes. Normal vision and normal bones are recessive traits. A man with cataracts and normal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones.
1. What is the genotype of the man with cataracts and normal bones?
2. What is the genotype of the woman with normal vision and fragile bones?
3. What type of offspring might this couple expect?
Answer:
- Cc ff
- cc Ff
- F1) 4/16 = 1/2 = 25% CcFf, cataracts and fragile bones
4/16 = 1/2 = 25% Ccff, cataracts and normal bones
4/16 = 1/2 = 25% ccFf, normal eyes and fragile bones
4/16 = 1/2 = 25% ccff normal eyes, normal bones
