A mutation modulating DDX3Y gene expression cosegregates with the major Y‐chromosomal haplogroups and with testis size in Hu sheep

24 days ago   |   By Animal Genetics

Summary
Variations in the Y-chromosome are usually correlated with male-specific traits. However, this condition has been described only sporadically, even in human genetics.

Consequently, we identified the full coding sequence and genomic sequence of ovine DDX3Y. Quantitative PCR analysis showed that ovine DDX3Y was highly expressed in testis, and the expression level...
