polyploid(genetics) an organism or cell having more than twice the haploid number of chromosomes
position effect(genetics) the effect on the expression of a gene that is produced by changing its location in a chromosome

recombination(genetics) a combining of genes or characters different from what they were in the parents
replication(genetics) the process whereby DNA makes a copy of itself before cell division
reversion(genetics) a return to a normal phenotype (usually resulting from a second mutation)
saltation(genetics) a mutation that drastically changes the phenotype of an organism or species
