Why 'y' chromosomes are obsolete nowadays?
They are not obsolete. Y chromosomes are what make males. When a child is conceived, they get two chromosomes: one from their mother, and one from their father. Since all women have two X chromosomes, the child gets an X from their mother. The father can give the child either an X or Y chromosome depending on the sperm that fertilizes the egg, since men have one X chromosome and one Y chromosome.

A child will be a girl if she receives what chromosomes from father and what chromosomes from mother?
A child's sex is actually determined entirely by his or her father. All eggs in a woman's body contain and X chromosome, whereas sperm cells contain either X or Y.

If the sperm contains a Y chromosome, the child will be a boy.

Which kind of chromosomes are necessary to produce a female?
There are two types of chromosome, called X and Y. Semen contains X sperm and Y sperm. If the Y sperm fertilises the female ovum, the child will be male. If the X sperm fertilises the female ovum, the child will be female. A man's chromosomes will be XY and a woman's chromosomes will be XX. The man's sperm always determines the gender of the baby.
What are the specific names of autosomal chromosomes like sex chromosomes?
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
Do you have a explanation about being a baby boy or girl?
Female humans have two X chromosomes, males have one X and on Y. The female contributes one X to the child. The male contributes either an X or a Y. This determines the sex of the child.

Chromosomes other than X and Y?
Chromosomes that are not X or Y are called homologous chromosomes and autosomal chromosomes. The first 22 pairs of human chromosomes are autosomal.
