- Analysis of X-Linked Dominant and Recessive Traits In the eighteenth century, a young boy with a skin condition known as ichthyosis hystrix gravior was identified. The phenotype of this disorder includes thickening of skin and the formation of loose spines that are sloughed off periodically. This man married and had six sons, all of whom had the same condition. He also had several daughters, all of whom were unaffected. In all succeeding generations, the condition was passed on from father to son. What can you theorize about the location of the gene that causes ichthyosis hystrix gravior?Duchenne muscular dystrophy is an X-linked, recessive disorder in which muscles waste away early in life, resulting in death in the teens or twenties. A man and woman in their late thirties have five children—three boys (ages 1, 3, and 10 years) and two girls (ages 5 and 7 years). The oldest, boy shows symptoms of the disease. What are the probabilities that their other children will develop the disease? Give only typing answer with explanation and conclusionThe following X-linked recessive traits are found in fruit flies:vermilion eyes are recessive to red eyes, miniature wings are recessiveto long wings, and sable body is recessive to gray body. A cross wasmade between wild-type males with red eyes, long wings, and graybodies and females with vermilion eyes, miniature wings, and sablebodies. The heterozygous female offspring from this cross, whichhad red eyes, long wings, and gray bodies, were then crossed tomales with vermilion eyes, miniature wings, and sable bodies.

- Hemophilia is another example of an X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia?Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___In humans, the ABO blood type is under the control of autosomal multiple alleles. Color blindness is a recessive X-linked trait. If two parents who are both type A and have normal vision produce a son who is color-blind and is type O, what is the probability that their next child will be a female who has normal vision and is type O?
- What is a Barr body? How many Barr bodies in a person with genotype XXXXX? How is the structure of a Barr body different from that of other chromosomes in the cell? How does the structure of a Barr body affect gene expression? Color-blindness is an X-linked recessive trait. Heterozygous females are not color blind but they can sometimes have partial color blindness. Explain how this can occur.In humans color vision is X-linked, the gene for color vision is located on the X chromosome but is absent on the Y chromosome. Normal color vision (XN) is dominant over colorblindness (Xn). Suppose a colorblind man fathers the children of a woman with genotype XNXN. What is the genotype of the father? What proportion of daughters will be colorblind? What proportion of the sons will be colorblind?Which of the following statements is false? Dosage compensation is accomplished in humans by stimulation of gene expression from the single X chromosome. Dosage compensation is accomplished in humans by inactivating a female X chomosome. An individual with Turner Syndrome has no Barr bodies. An individual with Klinefelter syndrome generally has one Barr body. A typical XX human female has one Barr body.
