Document Summary

A mutation in the genetic code that is actually ben- e cial. Large population, many die due to a catastophy, few individuals left and the genes represented are not representative of the old population and there wont be the same genetic stuff in the population bison example. An inversion is a chromosome re- arrangement in which a segment of a chro- mosome is reversed end to end. An inver- sion occurs when a single chromosome un- dergoes breakage and rearrangement within itself. Inversions are of two types: paracentric and pericentric. A mutation in the chromosome, a missing, irregular or extra portion of chromosomal dna. Chromosomal translocation non homologous chromosomes swap a portion of their dna with each other. Diploid the exchange of genetic material between homologous chromosomes that results in re- combinant chromosomes during sexual re- production. A mutation in the genetic code that is harmful to the organism two complete sets of chromosomes, one from each parent.
