In today’s research two indica grain types, KS-282 and Super Basmati which exhibited contrasting sodium chloride (NaCl) tension response had been used to determine cell civilizations.
Females have two X chromosomes (XX), and males have one X and one Y chromosome (XY). The reproductive cells, or eggs and sperm, each have only one set of 23 chromosomes. While an egg always carries an X chromosome, a sperm cell can carry either an X or a Y, so it is the sperm that determines gender.
