In principle, earlier Eves can also be defined going beyond the species, for example one who is ancestral to both modern humanity and Neanderthalsor, further back, an "Eve" ancestral to all members of genus Homo and chimpanzees in genus Pan. The American Journal of Human Genetics.

If MSCI evolved to suppress sex-ratio distorters, then genetic conflict might be both a proximate in the first two cases described above and ultimate cause of these patterns. Why is Mendelian segregation so exact? Plant Cell. However, the MLH1 foci in the sex bivalents were exposed differently.

BMC Biol. Segregation distorters give rise to genetic conflicts among loci, as natural selection favors alleles at unlinked loci that suppress distortion due to fertility costs associated with distortion and alleles in close linkage that enhance distortion [ 2 ].

Additionally, asynaptic and synaptic segments of the X were significantly thicker 3—5 times than the Y axis Figure 3 e,j, see inset. The edition sold a record number of copies. However, disruption of equal transmission of the X and Y chromosomes has the additional consequence of influencing the sex ratio of the progeny of carrier males hence, sex-linked segregation distorters are also called sex-ratio distorters.

In mice, the majority of X-linked protein-coding genetic conflict and sex chromosome evolution movie in West Jordan are down-regulated during MSCI, and most of these remain silent post-meiosis [ 23 ].

The publisher's final edited version of this article is available at Trends Ecol Evol. Orrorin Sahelanthropus Kenyanthropus. These intragenomic parasites can drive cycles of co-evolution between loci in the same genome, as the selfish locus adapts to exploit the host, and the host adapts to ameliorate negative effects of the parasite.
