Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? Use a punnet square. 2. A phenotypically normal man, who has a hemophiliac brother, marries a normal woman, who is not a carrier. What is the probability that any of their children will be hemophiliac? Use a punnet square. 3. Color-blindness is an X-linked, recessive trait. If a normal-sighted woman, whose father was color-blind, marries a colorblind man, what is the probability that they will have a son who is color-blind? Use a punnet square. 4. A man and woman, both of normal vision, have: 1) a color-blind son (#1) who has a daughter of normal vision 2) a daughter (#1) of normal vision who has one color-blind son and one normal vision son 3) another daughter (#2) of normal vision who has five sons, all with normal vision What are the probable genotypes of the…| 3 4 |IL 1 I Section 5: Trihybrid cross and Laws of probability For a trihybrid cross, in which inheritance of alleles for three genes is tracked, drawing a Punnett square that combines all three genes may not be practical. Instead the laws of probability may be used. The product law of probabilities says that when alleles for separate genes segregate independently, we can figure out the probability of a particular combined genotype by multiplying the probability of the alleles for each gene. 13.

- 1. Hemophilia is a disease inherited as a X-linked recessive trait while pattern baldness is controlled by an autosomal gene that is dominant in males and recessive in females. A hemophilic man who is also homozygous for baldness has children with a woman who is not hemophilic but a carrier and heterozygous normal-haired. Show the parental genotypes, the Genotypic ratio (GR) of the offspring and their phenotypic ratio. Separate the total number of the male offspring from female offspring. For example, if there are 8 total number of offspring, count how many are females and how many are males. So if there are 4 females, then the denominator for the genotypic ratio and phenotypic ratio for female offspring is 4. You can convert it to percentage if you want. Answer the following: a. Among the female offspring, what is the probability of having hemophilic but normal haired child? b. Among the male offspring, what is the chance of having a child with normal blood clotting but bald?4. Mr. Salazar has Type A blood while Mrs. Salazar has Type B. They have four children. Bobbie has Type A, Gabbie has Type B, Alex has Type AB, and Teddie has Type O. What are the genotypes of all six people in this family? NOTE: The ABO blood type gene has three alleles. IA and IB are codominant; i (for Type O) is recessive to both.1. Two people with wavy hair have a straight-haired child. Wavy hair is a dominant. What are the genotypes of the parents? What is the possibility that their next child will have wavy hair? Show the genotype and phenotype ratios that result from the above cross. Show the Punnett square.
