查询词典 progeny

Tetraploid embryo can be used as a power tool on life science such as on the research of mechanism in the inchoate embryo development which regulatory the cell volume, mumber and cleavage rate. Tetraploid embryo can also be used to change the ratio of genome of parents on the progeny; More importantly we can obtain completely ES cell-derived mice through tetraploid embryos complementation and the ES mice is significance in analysis of gene function and built disease mouse modle.
