Taggart, J. BMC Evol. Chromosomal sex determination in fishes with gills in Killeen 391—14 However, since females have a pair of X chromosomes originating from the ancestor of the WE lineage, with mitochondria phylogenetically close to this lineage in all the XY lineages except JB, which has recently experienced mitochondrial introgression 25 Fig.

Hybrid incompatibility was investigated in 20 crosses among 5 JO, JF, JB, EE, and WE lineages based on multiple facets of post-zygotic isolation, including fertilization rate, hatching success, larval survival, adult sex ratio, and fertility.

Moreover, the phylogenetic tree demonstrates that the X and Y haplotypes of these populations cluster together with the WE and JF populations, respectively Fig.

This was followed by the publication of a collection of classical papers on sex-linked pigmentation in fish. Evidence for multiple sex chromosomes in the freshwater goby, Gobionellus shufeldti Pisces: Gobiidae Copeia. In Metriaclima pyrsonotus , both systems occur [ ].

Caputo et al. In the case of the chicken, their Z chromosome is more similar to humans' autosome 9. In Pseudotropheus saulosi , coatomer protein complex subunit zeta-1 copz-1 might be involved in the development of color dimorphism [ ].
