Problema Solution
In a guinea pig, pure black hair coloring B is dominant over pure white coloring b. Suppose two hybrid Bb guinea pigs, with black hair coloring, are bred. What is the probability that two hybrid guinea pigs with black hair coloring will produce a guinea pig with white hair coloring?
Answer provided by our tutors
The probability is 0 for two hybrid Bb guinea pigs to produce a white fur guinea pig
Explanation:the only genotype that produces the recessive trait is homozygous recessive ("bb" in our example). So if an organism shows a recessive trait in its phenotype, its genotype must be homozygous recessive.
Here a form for more details:

Homozygous Dominant
(Pure Dominant)
BB

Heterozygous
(Hybrid)
Bb
Black
Homozygous Recessive
(Pure Recessive)
bb

So the probability for two hybrid Bb guinea pigs to produce a white fur guinea pig is 0
