Researchers from Johns Hopkins University and the University of Copenhagen analyzed over 139,000 embryos and identified variants in key meiosis genes, such as SMC1B, that influence chromosomal ...

As a group, carriers of recessive disorders are slightly less healthy and have a reduced chance of having offspring. This disadvantage is greatest for carriers of a recessive gene for intellectual ...

Scientists uncover how genetic factors influence reproductive timing, aging, and health, shedding light on fertility trends and their impact on future generations. Study: Genetics of female and male ...

Imagine suddenly losing your ability to smell certain foods; no longer sensing the aroma of fresh bread or ripe fruit. This is what happens to roundworms when they stop reproducing. They can still ...

The regulation of seasonal reproduction in sheep is intricately linked to the actions of melatonin, a hormone whose secretion varies with the photoperiod. Central to this process are the melatonin ...

A groundbreaking Indian study highlights the role of male factors in infertility and the potential of advanced genetic ...

A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood. Their results ...

In a groundbreaking experiment, researchers from the Chinese Academy of Sciences (CAS) have successfully created a bi-paternal mouse—a mouse with two biological fathers. This marks the first time a ...
