In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the Xor Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-inked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal allele but it can stiu be passed on through generations. Imagine a female is a carrier for hemophilia her genotype is Xx. She is married to a man who does not have hemophilia What conclusion is NOT vatid concerning this genetic cross?

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…

Jekyll-Hyde Afflicted Spider Curse Afflicted Jekyll-Hyde/Spider Curse I O Human 1 II 1 III 4. Jekyll-Hyde disease is characterized by transformation into an unfeeling, aggressive, alter ego at night. While the "Spider Curse" is a disease that causes affected individuals to grow extra arms and extra eyes during a full moon. The genes responsible for these diseases sort independently and both traits run in one family. Based on the above pedigree answer the following questions: What is the mode of inheritance for Jekyll-Hyde disease? (Hint: look at individuals III-1 & III-3) O a. Autosomal Dominant O b. Autosomal Recessive O c. X-Linked Dominant O d. X-linked Recessive What evidence supports your hypothesis? Give at least 2 pieces of information from the pedigree that support your answer to 3a. Answer: 2. 3. 2. 2.
