- Equalizing the Expression of X Chromosome Genes in Males and Females Males have only one X chromosome and therefore only one copy of all genes on the X chromosome. Each gene is directly expressed, thus providing the basis of hemizygosity in males. Females have two X chromosomes, but one is always inactivated. Therefore, females, like males, have only one functional copy of all the genes on the X chromosome. Again, each gene must be directly expressed. Why, then, are females not considered hemizygous, and why are they not afflicted with sex-linked recessive diseases as often as males are?5. A man who is not bald married a non bald female whose mother is bald. A. What is the chance that the couple will have a bald son? B. What is the probability that the couple will have a bald daughter? What is the chance that the couple will have a nonbald daughter? C.An attached-X female fly, XX ¬Y (see the “Insights and Solutions” box), expresses the recessive X-linked white-eye mutation. It is crossed to a male fly that expresses the X-linked recessive miniature-wing mutation. Determine the outcome of this cross in terms of sex, eye color, and wing size of the offspring.
- Barr bodies O are formed in females O are formed only in males cause an increased production of X-linked gene products O inactivate Xic on autosomes are formed only in males and inactivate Xic on autosomesThe maternal-effect mutation bicoid (bcd) is recessive. Inthe absence of the bicoid protein product, embryogenesis isnot completed. Consider a cross between a female heterozygousfor the bicoid mutation (bcd+/ bcd-) and a homozygousmale(bcd-/ bcd-). How is it possible for a male homozygous for the mutationto exist?. In humans, hemophilia is an X-linked recessive gene and will only be expressed in females if they are homozygous for this gene. However, in some rare cases, a heterozygote becomes hemophilic. Explain how this incident happens and why will there be skewed X-inactivation?
