13) A mutations causes the protein product to be altered or missing. Chromosomal Abnormalities. Entire chromosomes, or large segments of them are missing, duplicated, or altered. Multi-factorial Disorders. Result from mutations in multiple genes coupled with environmental causes.

15) Point Mutations only affect a SINGLE nitrogen base. May not cause any noticeable mutation if the amino acid is not changed. May also occur in the buffer or junk zones of DNA. Chromosomal Mutations affect entire or sections of a chromosome. Multiple Genes are affected. Always causes some type of change.
16) 1. Single Gene: Disorders caused by abnormality or mutation in the sequence of one gene. 2. Multifactorial: caused by a combination of environmental as well as mutations in multiple genes. 3. Chromosomal: Abnormalities in chromosome structure such as missing or extra copies. 4. Mitochondrial: caused by a mutation in the non chromosomal DNA of the mitochondria.
