Exercise 6: Sex-Linked Traits (XX) and males have an X and Y chromosome. During meiosis, sex chromosomes behave like other Humans and other mammals have two sex chromosomes X and Y. Females have two X chromosomes meiosis. Because females have two X chromosomes, all eggs have a single X chromosome. In males chromosome pairs. In humans, for example, sex chromosomes segregate with the autosome pairs during (XY), half of the sperm carry a Y chromosome and half carry an X chromosome. The X and Y chromosomes are not homologous, they do not contain matching genes. Genes found only in the X chromosome are X-linked, and genes found only in the Y chromosome are Y-linked. Together these are sex-linked genes. dominant gene H, you have normal blood. If you have the recessive gene h, your blood will not clot. Hemophilia is a disease in which the person's blood will not clot. The disease is inherited. If you have the Genes for hemophilia are located on the sex chromosomes. Only the X chromosomes have genes for hemophilia. Thus, a female can be XHXH, XHXh, XhXh. A male can be XHY or XhY. Procedure: Create a Punnett square for parents who are normal but the mother is a carrier for hemophilia. ; Mother's genotype: Father's genotype: What is the likelihood of the boys being hemophiliacs?_ Create a Punnett square for parents where the father has hemophilia and the mother is a carrier. Father's genotype:_ ; Mother's genotype:_ What is the likelihood of the boys being hemophiliacs? What is the likelihood of the girls being hemophiliacs?_
