Trihybrid Practice: You have freckles, dimples and a widow’s peak (You are heterozygous for all three traits). Your significant other has freckles and dimples (heterozygous for these two traits), but have a continuous hairline. Use the following information for your problem: ● Freckles (F) are dominant over no freckles (f); ● Dimples (D) are dominant over no dimples (d) ● Widow’s Peak is dominant over continuous hairline (no widow’s peak) (w) a) What is the probability that your child will have three recessive alleles: no freckles, no dimples, and a continuous hairline? Show your work to prove this correct
