Explanation:
Inherited traits are ones passed down from parent to offspring!
 
        
                    
             
        
        
        
Answer:
She has two recessive color blindness alleles.
Explanation:
The expression of arecessive phenotype requires both X chromosomes of the female to each contain a recessive color blindness allele. This genotype would the determine the mother would be color blind. 
 
        
             
        
        
        
Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result. 
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced: 
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
