Unisexual reproduction lacks meiotic recombination, resulting in the accumulation of deleterious mutations and hindering the creation of genetic diversity. Thus, unisexual taxa are commonly considered ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm's DNA. I describe ...

A team of researchers led by Professor Joseph Heitman has discovered procreation between genetically identical fungi Cryptococcus neoformans can result in genetic changes and diversity in their ...

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 ...

(Reuters) - Scientists in China have manipulated embryonic stem cells to create laboratory mice with two male parents that managed to live to adulthood - though with significant developmental ...

Unisexual salamanders of the genus Ambystoma constitute a unique vertebrate lineage that has persisted for millions of years through sperm-dependent asexual reproduction. These organisms employ ...

Chinese scientists have created the world’s first mice with two biological fathers and no mother that reached adulthood. This development marks a major milestone in reproductive biology and genetic ...

Researchers have bred a new species of all-female lizard, mimicking a process that has happened naturally in the past but has never been directly observed. "It's recreating the events that lead to new ...
