| Outline of Final Research Achievements |
In this study, using the Crispr / Cas 9 system, which is a genome editing technique developed in recent years, we knock-in genes that inhibit fertilization on sex chromosomes and inhibit fertilization of sperm having this gene, and aimed to develop technologies that enable birth separation. For this time, we planned the creation of male individuals having the desired gene in the X chromosome and not being able to fertilize sperm with X chromosome, that is, producing only male. As a result, genes were inserted in 3 lineage males, but male individuals bearing only males could not be obtained. Mating experiments are continuing also in other male lines, and in the recombinant female lines, a lineage of male recombinant mice is going to be established by crossing with wild type males.
