Unformatted text preview: b. Draw a map that shows distances in map units Calculated distance between v and b is 34.36 m.u. c. Calculate interference, if appropriate I = 1 – observed double crossovers/expected double crossovers I = 1 – 132/(.22 * .15 * 10,000) I = 0.6 v p b 22 m.u. 15 m.u. 2. John and Martha are contemplating having children, but John’s brother has galactosemia (an autosomal recessive disease) and Martha’s great-grandmother also had galactosemia. Martha has a sister who has three children, none of whom have galactosemia. What is the probability that John and Martha’s first child will have galactosemia? (Chapter 2, Q: #31) Use the product rule to calculate the probability that both parents are carriers (+/-) and that the child is -/- p(child has galactosemia) = p(Marth +/-) * p(John +/-) * p(both parents pass – to child) =2/3 * 1/4 * 1/4 = 2/48 = 1/24...
