Martha has widow's peak and attached earlobes. Martha's dad had a straight hairline and unattached earlobes. If Martha marries a man that is heterozygous for both traits, what is the probability that they will have a child with a widow's peak and attached earlobes?
Accepted Solution
A:
Answer:the probability of having a widow peak and attached earlobe = 0.6667*0.66667 = 0.4445 = 44.5%Step-by-step explanation:Martha = widow's peak + attached earlobes. Martha's dad = straight hairline + unattached earlobes. Martha husband =straight hairline+ widow's peak + attached earlobeswhat is the probability that Martha child will have a widow's peak + attached earlobes?since, Martha + Martha husband =straight hairline+ widow's peak + attached earlobesthe probability of the child having widow peak is 2/3 = 0.6667the probability of the child having attached earlobes is 2/3 = 0.66667the probability of having both = 0.6667*0.66667 = 0.4445
