Asexual reproduction, in which females reproduce without males by cloning themselves, has been documented in multiple species ...

A team of stem cell scientists successfully spawned mice from two male parents that reached adulthood, a significant step, but they still have to figure out the mechanics of the gene modification. In ...

Sharks, skates and rays adapt their growth and reproduction to changing food availability, a new study reveals.

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 ...

While some species of lizards and snakes can create new life via asexual reproduction, mammals rely on the union of male and female gametes for reproduction. 1 That was until a few years ago, when ...

For the first time, scientists have created a bi-paternal mouse – that is, a mouse with two male parents – which survived until adulthood. The breakthrough represents a huge step forward in the field ...

The researchers even coined a word for it, xenoparity, meaning “foreign birth”. It pushes the boundaries of what we mean by ...

In one of the largest studies of cancer susceptibility across bird species, researchers describe an intriguing relationship between reproductive rates and cancer susceptibility. In one of the largest ...
