because the male can either give an X or a Y
The male
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
Chromosomes. XX=female XY=male
It is called gamete. In animals the male gamete is always a sperm. In most flowering plants the male gamete is also called sperm.

Chromosomes. XX=female XY=male
The sex of the offspring is always determined by the sperm: this is the same in pretty well all animal life, including human reproduction. The gamete in a cow always carries the X chromosome. The gametes in a bull carry both X and Y chromosomes, which mean that if the sperm with an X chromosome fuses with the gamete of the cow, the offspring will be female. If the sperm carries a Y chromosome and fuses to the female gamete of the cow, then the offspring will be male.

Gamete
Gamete
Sex cells that unite are called gametes. In sexual reproduction, the male gamete, or sperm cell, fertilizes the female gamete, or egg cell, to form a zygote. This process combines genetic material from both parents to produce offspring.
A gamete. It might be a bit too broad though. In animals the male gamete is always a sperm. In most flowering plants the male gamete is also called sperm.
The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
The sex chromosome determines the sex of the organism. There are 46 chromosomes- 2 sex and 44 autosomes... the autosomes determine your traits, whereas the sex determine the sex; XX= FEMALE XY= MALE.
Gametes carry genes that determine the sex of an offspring.
