Imagine that you have two black dogs. one is black because it carries two dominant genes for black (bb). the other is black because it carries one dominant gene for black and one recessive gene for the recessive color liver (bb). use a punnett square to predict the phenotype and genotype for the offspring of a cross between these two dogs.

The correct answer would be:

Black is a dominant trait as it is expressed in heterozygous condition (Bb).

The genotype of one parent is BB. Thus, it would produce only one type of gamete that is, B.

The genotype of other parent is Bb. It would produce two types of gametes; B and b.

The cross will result in the production of puppies with two types of genotypes BB and Bb.

However, the phenotype of all the puppies will be black color as black is a dominant trait.

explanation:

they can be good for the ecosystem

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
