Hemophilia Procedure: Create a Punnett square that determines the probability of male offspring having hemophilia when the father has hemophilia (Y Xh) and the mother is a carrier (XH Xh). Record the results.
- What were the possible genotypes of the offspring?
- Out of only the male offspring, what is the probability (percentage) of a male being afflicted with hemophilia of only the male offspring?
- How many females (what number of females) would be expected to have hemophilia out of the entire population of offspring?
- How many carriers (what number of carriers) are expected to be produced out of the entire population? What sex are the carriers?

6. Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "XH” for normal and "Xh" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (XX) but a man will have only one allele (XY). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a. What are the genotypes of the parents? b....

Given the following genotypes: QqRRSs x QqrrSs, what is the probability of producing offspring that present only one dominant feature? Show your work. For a sex-linked disorder such as hemophilia, illustrate the punnett square and pedigree for the offspring of an affected male (X Y) and carrier female (X^AX^a). Show your work. What is the probability of having an affected daughter? What is the probability of having a normal male?

LAB EXERCISE 4.1 continued Name 6 Remember that the ability to taste PTC is dominant to the inability. Two normally pigmented taster parents have an albino, taster son and a non-taster daughter with normal pigmentation. Using A and Tand a and t for the dominant and recessive alleles, respectively, create a Punnett square for two traits, as shown on pages 71-73 in the section "Transmission of Autosomal Traits: Two at a Time."...

4. Now, assume that a F1 male and a F1 female offspring produced by the cross in #3 above mate with each other. F1 offspring : XXGgBb and XYGgBb Note: You can ignore the X and Y chromosomes here in question 4. Why? The traits of interest (fire-breathing and laser-shooting) are autosomal, so the sex of the fly (XX=female or XY=male) will not impact the trait expressed. You only need to follow the inheritance of chromosomes 2 and 3 for...
