n 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 short ears?
(You may use the easy quick method to solve. Hint= set up 2 monohybrid crosses and multiply the results)
a
1/16
b
3/16
c
6/12
d
9/16
To determine the probability of the offspring being black with short ears, we need to set up two separate monohybrid crosses for each trait and then multiply the results.
First, let's set up the monohybrid cross for fur color:
Ww x Ww
The possible genotypes of the offspring will be:
WW, Ww, Ww, ww
The probability of getting black fur (ww) from this cross is 1/4.
Now, let's set up the monohybrid cross for ear length:
Ee x Ee
The possible genotypes of the offspring will be:
EE, Ee, Ee, ee
The probability of getting short ears (ee) from this cross is also 1/4.
To find the probability of two independent events occurring, we multiply their probabilities together. So the probability of getting both black fur and short ears is:
(1/4) x (1/4) = 1/16
Therefore, the answer is choice a) 1/16.
