Spotteddog Interactive BioStudio:Genetics
In dogs, black coat color [B] is dominant to red coat color [b], and solid coat [S] is dominant to spotted coat [s]. Question: If a dog with a solid black coat (genotype: BbSs) is crossed with a dog with a spotted black coat (genotype: Bbss), what percentage of the puppies will have a spotted black coat, assuming the two genes are unlinked (show independent assortment?
Lets figure out the percentage by constructing a Punnett square!
First enter
in the alleles
for the gametes
of Parent 1 and Parent 2.
Then fill in the Punnett square.
Here is the cross you should perform!
