 |
Classical pedigree based study of genetics of semen quality and fertility of crossbred bulls (Frieswal, Karan Fries and Vrindavani) |
|
Comparative gene expression difference, between good and poor quality semen producing bulls, involved in developmental pathways, sperm motility & fertilizing ability, sperm membrane integrity and energy metabolism |
|
Differentially expressed testicular genes involved in various important pathways (sperm motility & fertilizing ability, sperm membrane integrity, ion channels and energy metabolism etc.) between good and poor performers in all the three crossbreds |
|
Detection of Y chromosome deletion/ microdeletion patterns in crossbred bulls derived from taurus and indicus males and their involvement in semen quality parameters |
|
Elucidation of the imprinting level of H-19 and SNRPN genes in the testicular tissues and ejaculated spermatozoa and their association with male fertility status |
|
Effect of sperm of different motility and gene methylation status on embryonic development will be evaluated |
