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 ...

A gene-edited mouse created with two male parents has now survived to reach adulthood. This is a momentous occasion for genetics, as previous attempts to create bi-paternal mice have failed for a ...

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 ...

Quick Take Preserving the northern white rhino now requires overcoming functional extinction, as there are only two females ...

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 ...

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 ...

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 ...

Led by researchers from the University of Oxford’s Leverhulme Centre for Demographic Science and the University of Iceland, the review explores how genetic variations can explain differences in ...

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 ...
