F or the first time, researchers have fused two mouse chromosomes together in vitro, resulting in living mice with new karyotypes. The new technique, detailed in a study published today (August 25) in ...

Evolutionary chromosomal changes may take a million years in nature, but researchers are now reporting a novel technique enabling programmable chromosome fusion that has successfully produced mice ...

Live mouse progeny can be generated with assisted reproduction using germ cells from males without any Y chromosome genes. In these males, the two Y genes previously demonstrated to be essential ...

We're a step closer to two men being able to have genetic children of their own after the creation of fertile mice by putting ...

Males imprint their DNA by adding methyl modifications to it in a way that alters the activity of genes in order to promote ...

The laboratory mouse has a standard karyotype of 40 chromosomes. This consists of 19 pairs of autosomes plus the X and Y chromosomes. Engineering large-scale changes to this set has been ...

The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the ...

In the new experiment, the mice were missing the gene because they didn’t have Y chromosomes. So researchers substituted a similar gene from the X chromosome called Eif2s3x .

Scientists have created genetically-engineered mice with artificial human chromosomes in every cell of their bodies, as part of a series of studies showing that it may be possible to treat genetic ...

Jacob Kastrenakes is The Verge’s executive editor. He has covered tech, policy, and online creators for over a decade. Males are supposed to need a Y chromosome to reproduce — it’s what’s ...

Male mouse with two x chromosomes created ADELAIDE, Australia, Aug. 21 (UPI) -- Australian scientists discovered a way of creating a male mouse without a Y chromosome by manipulating a single gene ...

For males, Y chromosome are needed for reproduction, as it makes the testes. But scientists just discovered that male mice can breed without it.
