Spermatozoa are highly differentiated cells whose ultimate function is fertilization to
successfully transfer the male genome. This achievement relies on the expression …

Hybridization is important for both animal breeders attempting to fix new phenotypic traits
and researchers trying to unravel the mechanism of reproductive barriers in hybrid species …

Abstract Background Alpaca (Vicugna pacos), llama (Lama glama), vicugna (Vicugna

adapt to the harsh environmental conditions of the Qinghai Tibet Plateau (QTP). However …

German Black Pied cattle (Deutsches Schwarzbuntes Niederungsrind, DSN) are an
endangered dual-purpose cattle breed originating from the North Sea region. The …

ProAKAP4 is identified within the flagellum of spermatozoa in various mammalian species,

link between homologs for proper chromosome segregation as well as ensure genetic …

The variety of species can be efficiently increased by interspecific hybridization. However,
because the males in the hybrid progeny are usually sterile, this heterosis cannot be …
