Question

In a breed of dogs, there are two alleles for fur color, "B" and "b.* When a dog is "BB"

or "Bb", the dog has black fur. When the dog is "b", the dog has white fur. Which best
describes the number of genotypes and phenotypes that exist in this breed of dogs?​

Answer 1

there will be 3 genotypes that exist in this breed of dog (BB, Bb and bb) and there will be 2 phenotypes (Black fur and white fur) B is the dominant allele and is always shown when present while b is the recessive allele and is only shown when there’s no dominant allele present. This means that dogs with BB and Bb alleles will have black fur (since the dominant, which is B, is present) and dogs with the bb alleles will be white since there’s no dominant allele (B) present

i hope this helps

Answer 2

I would say I would say three “BB, Bb, bb.” Could be a mix.

bb would probably be less dominate while BB is going to win

BB- homozygous dominate, shows more of the trait/gene
bb- homozygous recessive, not really showing/ BB is still dominate
Bb- heterozygous, trait shows
