However, this advantage is countered by the fact that haploid males will probably be less viable, at least in the early stages, which will limit the origination of haplodiploidy. Biased introgression of mitochondrial and nuclear genes: a comparison of diploid and haplodiploid systems.

For example, most lineages of male Drosophila melanogaster flies are achiasmic, lacking recombination on all chromosomes, although females show recombination. The bp first reads within each individual plant were grouped into tag reads based on sequence similarity by allowing a maximum of two mismatches between any two RAD reads.

This generated million reads, comprising approximately The number of RAD tags in this study was 9. Then, if they succeeded to distinguish the sex of F 1 progenies, they were tested using 17 male and 47 female cultivars in the germplasm collection previously characterized by Kafkas et al.
