Chinese scientists create the world
The first “chromosomal fusion” mouse
On August 26, the top issue of Science reported a major study. A scientific research team led by Academician Zhou Qi of the State Key Laboratory of Stem Cell and Reproductive Biology, Institute of Zoology, Chinese Academy of Sciences, used haploid embryonic stem cells and gene editing technology to create a special “chromosomal fusion” mouse: in their In a cell, two chromosomes “merge into one”, resulting in a total of 19 pairs of chromosomes. Moreover, this fusion chromosome can also be passed on to offspring.
The researchers’ analysis found that the reduced fertility caused by carrying the new fused chromosomes is due to an abnormality in the way the rearranged chromosomes segregate. This finding demonstrates that chromosomal rearrangements are important for establishing reproductive isolation — a key evolutionary hallmark of the emergence of new species.
