Unformatted text preview: Problem Set 6 Name: Answer Key _______ Genetics 0350 Martens Due April 3, 2008 at 2:30 pm 15 point total 1) 8 points total. The discovery of chromosome banding in eukaryotes has greatly improved the ability to distinguish various cytogenetic events. Particularly useful are alterations of banding patterns as a result of changes in chromosome structure. These polymorphisms make chromosomes cytologically distinguishable after staining by virtue of band sizes, positions, and distributions. Considering just chromosome 18, the parents of a baby have chromosomes 18 e 18 p (female parent) and 18 e 18 m (male parent) where e, p, and m represent different polymorphisms for chromosome 18 as detected by staining. Staining of the babys chromosomes reveals the following: 42 autosomes + 18 e 18 e 18 m + XY a) What is the term for this class of chromosomal abnormality? Trisomy b) What is the specific name of this syndrome? Edwards Syndrome c) Diagram the abnormal meiosis that could have given rise to this condition in the baby, indicating...
