Gene recombination of genes

Recombination of genes makes possible the genetic diversity of people. Jeffries and colleagues were able to localize the DNA regions where most of the recombinations occur and isolate the gene that encodes the protein that provokes this phenomenon.

Defenders of the rights of embryos: expert comment

Does it make sense to discuss the possibility of using 50-100 blastocyst cells for the benefit of science and in the name of a chance to cure many patients, which should be destroyed, while abortion of a three-month-old fetus is legally allowed in many countries?
