Answer:
Probability that child has wet earwax phenotype = 50 %
Step-by-step explanation:
To solve, we just need to look at the possible outcomes:
Wet Earwax Dominant allele : W
Dry Earwax Recessive allele : w
Parent 1 : W-w
Parent 2 : w-w
The possible outcomes are four:
W - w
w - W
w - w
w - w
Child having Wet earwax phenotype will have combination : W-w or w-W
Probability that child has wet earwax phenotype = [tex]\frac{2}{4}[/tex]
Probability that child has wet earwax phenotype = [tex]\frac{1}{2}[/tex] = 0.5 or 50%
