- 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?Fragile-X syndrome causes the most common form of inherited intellectual disability. What is the chromosomal abnormality associated with this disorder? What is the phenotype of this disorder?Why is 26 incorrect

Even though neither of them had the disease, they wanted to know Before Sam was born, his parents decided to go for genetic counseling. They knew that sickle if they had a chance of having a child with the disease. Genetic Counseling Sam's parents to have a child with sickle cell disease. That was why Sam and his brother or helped his parents to provide Sam with the earliest possible diagnosis. They understood disease and were prepared to provide Sam with the best treatments available. They beoe involved with the Children's Sickle Cell Foundation and took part in the support groups. Gene counseling prepared Sam's parents to help Sam deal with the sickle cell disease. Pedigrees used by genetic counselors often include other information about the families Ao dates of birth, and dates of death are often included.

It appears that this HeLa cell (look at picture) has _______ extra copies of chromosome one.A small fraction—2 to 3%—of all cancers, acrossmany subtypes, displays a quite remarkable phenome-non: tens to hundreds of rearrangements that primarilyinvolve a single chromosome, or chromosomal region.The breakpoints can be tightly clustered, with several in afew kilobases; the junctions of the rearrangements ofteninvolve segments of DNA that were not originally closetogether on the chromosome. The copy number of varioussegments within the rearranged chromosome was foundto be either zero, indicating deletion, or one, indicatingretention.You can imagine two ways in which such multi-ple, localized rearrangements might happen: a progressiverearrangements model with ongoing inversions, deletions,and duplications involving a localized area, or a cata-strophic model in which the chromosome is shattered intofragments that are stitched back together in random orderby nonhomologous end joining (Figure Q20–2).A. Which of the two models in Figure Q20–2 accountsmore readily for the features of…
