In mammals, the Y-linked SRY gene is normally responsible for testis induction, yet testis development can occur in the absence of Y-linked genes, including SRY. The canine model of SRY-negative XX sex reversal could lead to the discovery of novel genes in the mammalian sex determination pathway. The autosomal genes causing testis induction in this disorder in dogs, humans, pigs, and horses are...

Genetic crosses between the dioecious Bryonia dioica (Cucurbitaceae) and the monoecious B. alba in 1903 provided the first clear evidence for Mendelian inheritance of dioecy and made B. dioica the first organism for which XY sex-determination was experimentally proven. Applying molecular tools to this system, we developed a sex-linked sequence-characterized amplified region (SCAR) marker for B....

conclusions albumin gradient method is the enrichment of y-bearing chromosome sperms. separation of spermatozoa by albumin gradient method, introduced by ericsson, is a suitable method for sex selection of male offspring. this technique is safe, because it neither requires toxic materials during sperm separation, nor involves embryo manipulation. objectives the study aimed to assess the separat...

The swimming crab Portunus trituberculatus is an economically vital aquaculture species in China and South East Asia. Monosex female culture has been identified as a key priority due to their increased market value, consumer preference enhanced growth performance. However, the lack of rapid reliable sex-linked marker panel hampered application sex control understanding determination species. In...

a study was conducted to identify ssr markers linked to leaf rust resistance genes lr24 and lr28 and to be used for marker-assisted selection (mas) to transfer both genes to a widely cultivated wheat variety mp 3299 under rainfed condition. f2 individuals of the cross mp 3299×nil pbw 343 were used for generating genotypic data employing closely linked scar markers s73719 and s421570 to lr24 and...
