All right, so in rabbits, the autosomal alleles for black fur is big b.
00:03
It's dominant over the alleles for white for little b.
00:06
Suppose a rabbit with black fur is crossed with a rabbit with white fur, what phenotype and genotype percentages could this cross produce? how could you be certain other parents ' rabbits genotype? use point squares to showwork.
00:17
So we have our allele given.
00:19
We have b for black, little b for white, and a rabbit with black fur is crossed with a white fur.
00:31
So our black parent could be either bb or bb, and then the white parent will be little b, little b, little b.
00:45
So if the rabbit parent was homozygous b and white, progeny will be, so it would look like this, there's a funnet square, we have a heterozygote, we have a homozygo, homozygo, and another heterozygo...
