13, The chromosome doubling of haploid and double haploid in cucumber was studied.
14, A yeast haploid S1(a) with high intracellular content of reduced glutathione (GSH) was selected from 75 yeast strains by primary screening and isolation of haploid, and then marked with auxotroph.
15, For example, if the haploid number is 7, the euploid number would be 7,14,21,28, etc, and there would be equal numbers of each different chromosome.
16, Mononucleated haploid cells join to produce binucleate cells.
