Document Summary

Cnp - copy number polymorphism, 1% or greater of the population. Neutral mutation: a mutation that has no effect on fitness. In other words, it is neutral with respect to natural selection. Mutations can be in regulatory elements and have effects on expression. Discordant for a phenotype - one individual has it, one does not. Non-allelic - means they are similar but not identical and they can facilitate crossing over between the two strands. Satellite repeats large, tandemly repeating non coding, ie. centromeres, heterochromatin. Gene sets - computer program can identify common pathways within the gene set. It is the origin and development of an organism. From fertilized egg to mature form of an organism"s lifespan. Somatic mosaic - occurs when the somatic cells of the body are of more than one genotype. We are mosaics of mutation in mitochondrial dna.
