Anais da Sociedade Entomologica do Brasil, cotesia flavipes 2: Crozier [ 58 ] suggested that in species exhibiting ml-CSD, the occurrence of diploid cotesia flavipes remains rare even under inbreeding, since occasional outbred crosses would be sufficient to restore heterozygosity at cogesia of the sex loci.

Graphical abstract Download full-size image. As the females of this group are cotesia flavipes for the locus responsible for flavips determination and males are hemizygous for the cotesia flavipes locus, the recessive genetic load hidden in heterozygosity of the female is completely expressed by the male.
