A human with an XY chromosome pair appears female. What might explain this person's condition? O This person has an extra copy of the SRY gene. O This person suffers from Turner syndrome. O This person has a mutated SRY gene. O This person suffers from Angelmansyndrome. O The XY determination was an error because it is impossible for a human XY individual to be female.
1.Describe the rearrangement in chromosomes A-C. indicate the specific markers genes flanking the crossover/breakage points (e.g., a translocation with breakpoints between markers X and Z). 2.Chromosome rearrangements can be caused by crossing over between repetitive DNA sequences. Draw a picture similar to Figure showing how crossovers between repetitive sequences could have produced chromosome rearrangement A. indicate the location and orientation of the repetitive DNA segments relative to the marker genes.
