Sperm quality, aggressiveness and generation turnover may facilitate unidirectional Y chromosome introgression across the European house mouse hybrid zone.

abstract：:Although allelic variants at a locus usually are expressed either dominantly or co-dominantly, there are many cases when a gene is dominantly expressed in some individuals and co-dominantly in others. We present a maximum-likelihood procedure for allele frequency estimation in such situations of "incomplete" co-domina...

To be of value as a bio-marker to highlight conditions at particular sites, it is important that variation in FA is due to environmental (eg pollution) variation and not geneti...
