Document Summary

Adaptations: traits that have evolved by natural selection. Any change to genomic sequence in an organism. Gene expression can be regulated by a number of ways. Can act like a switch to turn on and off. Can leave the cell and go to another one. Used to be functional gene but then mutations made it non-functional. Most variation in size due to differences in mobile genetic elements. Polyploidy in plants gives them a lot more regulatory sequences. Also a lot more dna to work with. Dna is stable -- encodes for proteins, if mutated, can alter protein. Mutations to noncoding rna can affect the translation and expression of genes. Key words: epigenetics, pseudogenes, genome, polyploidy, microrna, gene expression, gene regulation, mobile element. Albinism, polydactely, poly something, piebaldism, the thing zack has, microcephaly hutcheson syndrome. Rate of different types of mutations happen at different rates. Single gene produces many phenotype depending on environment.
