Genetic Disorders Autosomal and Sex-linked. HOW DO WE GET GENETIC DISORDERS? Nondisjunction – failure of chromosomes to separate during cell division.

Types of Chromosome Mutations. Aneuploidy (2n +/- m) Aneuploids differ from wild-type individuals by part of a chromosome set. Nondisjunction is a common.

Chromosomal Abnormalities You’ve seen the genes! Now you’ll see the chromosomes! Oh What Fun!
Chromosome Abnormalities. I. Chromosome Terms A. Autosome – chromosomes that are not involved in determining the sex (gender) of an individual. (22 pairs.
