Question

The numbers of chromosomes in woman gamete are
(A)23
(B)46
(C)32
(D)48

Answer 1

The number of chromosomes throughout the body (somatic) cells is usually diploid; double the haploid (1n) number present within gametes or sex cells, in organisms that reproduce sexually.

Complete answer:
First, we should know about chromosomes to answer this question. A chromosome is a lengthy molecule of DNA with some or more of an organism's genetic material. Many eukaryotic chromosomes contain packing proteins known as histones that attach and condense the DNA molecule to preserve its integrity, supported by chaperone proteins. These chromosomes show a complex three-dimensional structure that plays an essential role in transcriptional control.
Now, let us find the solution from the options-
- The human system of sex differentiation is XX-XY, wherein females possess forty-six chromosomes distributed in twenty-three homologous, homomorphic pairs.
-There are twenty-two homomorphic pairs for males or one heteromorphic pair, the pair XY. Both gametes formed by females comprise only the X chromosome throughout meiosis (22 A + X; total 23), while males develop two forms of gametes, 1/2 X-gametes and 1/2 Y-chromosome gametes i.e. 22 A + X as well as 22 A + Y, thus the total is 23.
Egg fertilisation of 22 + X of sperm bearing 22 + Y chromosomes resulting in a total of 46 in a female foetus with 44A + XX. Egg fertilisation with sperm bearing 22+Y chromosomes resulting in male offspring, i.e. 44A + XY; there are 46 chromosomes in total.

Hence, the correct answer is option(A)

Note: The chromosome number will always be the same in any provided asexually reproducing organisms. An individual with some number of diploid chromosomes is known to be polyploid.
