Document Summary

Sizeable pop one mutation wont affect the allele frequencies by much. Substitution: switches the nucleotide (changes sequence: frameshift will shift the nucleotides (insertion, deletion, inversion can involve many things. Same sense : sub but code for same aa. Can still have a phenotypic affect (can affect the rate of transcription: nonsense stop codon early, missense changes the nucleotides. Can have a huge big duplication in chromosome and big impact sickle cell point mutation. Sub changes the amino acid (glu > val) Not a same sense, change in aa sequence. In crossover (in germ cell) get a duplicated section. The 2nd copy could accumulate useful mutations which could be subject. : also could have more exibility for regulation and get. Common have very similar stretches of nucleotides. Mammals 3 groups: monotreme (lay eggs and nurture young, marsupials (i. e. kangaroos, placental (biggest group)
