How to Calculate the Odds of Inheriting Recessive Traits

What are the odds of your child inheriting both teal hair and stumpy toes if neither you nor your spouse exhibit these traits?

a) 25%

Answer:

The odds of your child inheriting both teal hair and stumpy toes would be 25%.

When neither you nor your spouse exhibit teal hair or stumpy toes, but your mother has teal hair color, your father has stumpy toes, and your new father-in-law has both traits, the odds of your child inheriting both can be calculated based on probability.

The probability of your child inheriting teal hair color from your mother, who has a recessive trait, is 50%. Similarly, the probability of inheriting stumpy toes from your father is 50%. Since your new father-in-law has both traits, the probability of your child inheriting both is calculated by multiplying the individual probabilities: 50% x 50% = 25%.
