In rabbits, white fur (W) is dominant to black (w), and long ears (E) are dominant to short ears (e).
A breeder mates two rabbits that are heterozygous (WwEe) for both traits.
What is the chance that the offspring will be black with long ears?

Balaenoptera

Answer:

3:16

3 individuals of the 16 offspring will exhibit black coat and long ears.

Explanation:

Both parents are heterozygous for both traits so they exhibit the following genotype: WwEe, normally known as a Dihybrid organism.

In this case black is recessive and long ears is dominant. So, we are looking for offspring with black (w) and long ears (E).

Let's create the Punnett Square and see what the offspring will look like and the chances of the offspring of showing black coat and long ears.

          WE              We             wE            we        

WE    WWEE       WWEe      WwEE     WwEe

We    WWEe       WWee      WwEe      Wwee          OFFSPRING

wE    WwEE        WwEe      wwEE      wwEe

we    WwEe        Wwee      wwEe      wwee

In this case, the underlined genotypes are the offspring that exhibit black coat (ww) and long ears (EE or Ee). Therefore the ratio will be: 3:16 (3 individuals from 16 individuals in total).
