The father provides an X or Y chromosome; the mother always provides an X chromosome. Therefore, the sex of the child is determined by the chromosome of the individual sperm that fertilizes the egg.

Male offspring carry XY chromosomes; female offspring carry XX chromosomes.

Information from another contributor

  • the father deposits the semen containing sperms in the vagina of mother. ideally the X and the Y sperms are in same number (this is rarely the case).
  • the germ cell in father's testicle initially divides into 2 cells. one of which is Y sperm responsible for male child. second one is X sperm responsible for female child. These cells then each divide in 2 these 2 cells further divide in 2 each producing 4 of one kind. this process goes on and on to produce 50 millions to 150 millions sperms in the semen. Half of them are Y sperms and Other half are X sperms.
  • If the X sperm unite with female egg then a female child is born.
  • If Y sperm unite with female egg then a male child is produced.
  • As same number of Y and X sperms are deposited in the vagina; which type of sperm ultimately will unite with female egg depends on the conditions of female reproductive system. Whether the condition is favorable for the rapid and safe movement of X sperms or the Y sperms.
  • The Y sperms are very delicate and are easily get destroyed by acidic and toxic environment of vagina. Thus if the vagina is very acidic most of the Y sperms are destroyed the rest may get immobile and not fit to swim in the cervical canal.
  • The X sperms are stronger and can withstand the acidity and toxicity better.
  • Thus if the medium of the reproductive organ mainly vagina, cervix, uterus and fallopian tubes is not favorable then the Y sperms get destroyed or immobile and the surviving X sperms swim in to unite with X egg of the woman to produce female child. This is why failure of family planning method like condom, spermicides, jelly, or withdrawal mostly results in female child. Similarly women having vaginitis, cervicitis, leucorhea, candida infection, cervical erosion almost always produce female children.

In humans, it is the sperm which determines the sex of the child. The presence of a Y chromosome in the zygote is what determines that the child will be male. Only the father has a Y chromosome (XY).

Sex-linked traits have alleles that are passed from parent to child on a sex chromosome.

The presence or absence of a y chromosome determines the sex of an individual. If a child had received a y chromosome from the father it is a boy, if it has received an x chromosome from its father is a girl. A child always receives an x chromosome from its mother, thus it is always the fathers contribution that determines the sex.

Many things are taken into consideration when determining an unfit parent. If a parent neglects their child, they are unfit.

The sex of a child is determined by the sex chromosome of the sperm cell (which comes from the father). If it is a Y, the child will be a boy, if it is an X, the child will be a girl.

No the mother only has a single sex chromosome, an X chromosome. The father is the one who determines the gender of the child. They could contribute either an X or Y chromosome. Remember you get one sex chromosome from each parent. X X- you're a female. X Y- you're a male

A parents sex chromosomes hold DNA. A parents DNA is passed onto the child.

The fathers because the mothers is always female.

These alleles are called sex-linked alleles or traits.

the males X and Y chromosomes and the females X chromosomes

both X and Y chromosomes in their sperm

It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
