Evolution - ANS Change in frequency of traits in a population. The process of change that has transformed life on Earth from its earliest forms to the vast array of organisms living today. Descent with modification - the idea that living species are descendants of ancestral species that were different from present-day ones. Genetic changes in a population from one generation to the next. Natural Selection - ANS Cause of change.

Karyotying - ANS - To determine if there's an abnormal number of chromosomes. (due to nondisjunction, ex down syndrome) Pedigree Analysis - ANS - To determine whether a gene is dominant/recessive and on the X chrom vs autosomal. Down Syndrome - ANS Caused by an extra copy of chromosome 21 ("Trisomy 21") Turner Syndrome - ANS woman missing an X chromosome (XO) - Not fatal, even though there are only 45 chromosomes - Normal intelligence, but short height and web of skin between neck an...
