the effects of central fusion , terminal fusion on heterozygosity


parthenogenesis natural form of reproduction in growth , development of embryos occur without fertilisation. thelytoky particular form of parthenogenesis in development of female individual occurs unfertilised egg. automixis form of thelytoky, there different kinds of automixis. kind of automixis relevant here 1 in 2 haploid products same meiosis combine form diploid zygote.


diploid artemia parthenogenetica reproduce automictic parthenogenesis central fusion (see diagram) , low nonzero recombination. central fusion of 2 of haploid products of meiosis (see diagram) tends maintain heterozygosity in transmission of genome mother offspring, , minimise inbreeding depression. low crossover recombination during meiosis restrains transition heterozygosity homozygosity on successive generations.
