who decides the sex of the baby mother or father?explain with a flow chart
Answers
Answer:
The sex or the gender of the baby is determined by the father.
Explanation:
The reason is, the baby is formed by the combination of two chromosomes. One half is obtained from the mother and second half is obtained from the father.
Now, a girl will always possess only XX chromosomes while a male will have both X and Y chromosomes. Hence the mother gives one half of her combination which is 'X' chromosome.
Now if the second half obtained from father is also 'X', then the resulting baby will be a female having a combination XX.
If the second half obtained is a 'Y', then the resulting baby will be a male having a combination XY.
Since the chromosome from father decides the gender of a baby, he is responsible for the determining the sex of the baby as well.

Answer:
The sex of the baby is depended on the father.
Explanation:
In the case of the human, the male individual possesses sex chromosome (XY) in addition to their normal autosome, similarly female individual contains XX chromosome as sex chromosome along with their number of autosomes.
It is therefore thought that genes for femaleness is associated with the X chromosomes and genes for maleness are on Y chromosomes.
Hence, the presence of the Y chromosome is a must for the determination of sex of the male person. When fertilization takes place between a sperm carrying the X chromosome and an egg cell with the X chromosome; then, the developed zygote will contain an XX combination, the child will be a girl.
If a sperm carrying Y chromosome unites with an egg cell containing the X chromosome then the zygote will carry XY chromosome and the child will be a boy.
⟹ Hence, it can be concluded that the sex of the baby is depended on the father.
