Structures present in a cell which is responsible for determination of the sex of a baby is
The correct option is D chromosome
The correct option is Option D.
The explanation for the correct option:
There are 23 pairs of chromosomes present in a human cell among them 22 pairs are autosomes and 1 pair is a sex chromosome.
- Sex chromosomes are different for males and females.
- Sex chromosomes present in a male are XY and those present in a female are XX.
- There are no differences in the cytoplasm or membrane.
- Male produces two types of gamete, one contains the X chromosome and one contains the Y chromosome in the haploid stage, While the female produces a single type of gamete which is X.
- When the X chromosome of the male fuses with the X chromosome of the female the child will be a Girl having XX gametophyte.
- When the Y chromosome of the male fuses with the X chromosome of the female the child will be a Boy having XY gametophyte.
The explanation for the Incorrect option:
Option A:
Cytoplasm does not contain any molecule which transfers from one generation to another.
Option B:
The cell membrane is not suitable for the determination of the sex of the baby because it does not contain any genetic information.
Option C:
The nucleus is the cell organelle that contains genetic information but sex determination is not possible from it unless we are taking chromosomes in the picture as per option the chromosomes seem to be the best option in it.
Final answer: Structures present in a cell that is responsible for the determination of the sex of a baby are Chromosomes.
