LIFESCI 7B Lecture Notes - Lecture 7: Angelina Jolie, Tumor Suppressor Gene, Sister Chromatids
Document Summary
Edward brooke"s is in somatic cells, so no germ line. 4 haploid gametes-- 2 would have the mutation. What do we mean when we say a mutation is rare. Rare mutation: assume no mating will bring in the mutant allele into the population no individual mating into the pedigree will bring that allele with them bc his mutation was in somatic cells/tissue, does not get passed down. Mutations can also happen at the chromosomal level. Turner syndrome karyotype -- occurs with individuals with only 1 x chromosome -- instead of 2 copies, 1 copy. Melott 2 mother e variation exists in all populations genetic variation: based on the copy of the allele for that gene. Complex traits are a ected by multiple genes blood pressure, obesity, depression. Gene vs environment some do better than others grow in the same environment but do not look the same henotype bothresponding.
