it is determined by which parent give the chromosome. if the y chromosome is in it will be a girl and if it will be a boy.
The sex chromosomes, X and Y, determine the gender of one's offspring. An X and a Y is a boy, and 2 X's is a girl.
X and Y chromosoms determine whether or not an offspring is a male or female. Chromosomes come in pairs. Boys have an X and a Y chromosome pair; girls have an X and an X chromosome pair.
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
