BIL 150 Lecture Notes - Lecture 19: Mitosis, Meiosis, Genetic Testing
Document Summary
Dominantly inherited disorders: dominant alleles that cause a lethal disease are rare and arise by mutation. Multifactorial disorders: many diseases have both genetic and environmental components, ex: heart disease, cancer. Little is understood about the genetic contribution to most multifactorial disease. Medellin inheritance has physical basis: mitosis and meiosis were first described in the late 1800s, the chromosome theory of inheritance states, mendelian genes have specific tools. The chromosomal basis of sex: humans and other mammals, 2 varieties of sex chromosomes/ larger x and smaller y.
