Question

The diploid(2n) number of chromosomes for humans is
A. 22
B. 23
C. 44
D. 46

Answer 1

Hint:- A chromosome is an organised package of DNA found in the nucleus of the cell.Different organisms have different numbers of chromosomes. Humans have 23 pairs of chromosomes- 22 pairs of number chromosomes called autosomes, and one pair of sex chromosomes., X and Y.

Complete step-by-step solution:-Diploid describes a cell that contains two copies of each chromosome. Nearly all the cells in the human body carry two homeologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells. Germline cells are haploid, Which means they contain a single set of chromosomes. In diploid cells, one set of chromosomes is inherited from the individual's mother, while the second is inherited from the father.
Humans have 46 chromosomes in each diploid cell. Among those, there are two sex determining chromosomes, and 22 pairs of autosomal, or non-sex chromosomes. The total number of chromosomes in diploid cells is described as 2n, Which is twice the number of chromosomes in the haploid cell (n).
Ploidy is a number of complete sets of chromosomes in a cell, and hence the number of possible allets autosomal and pseudo autosomal genes. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present..
The generic term polyploid is often used to describe cells with three or more chromosome sets.
So from above discussion we can conclude that correct answer is option D

Note:-
Ploidy is a number of complete sets of the chromosomes in a cell. Human diploid cells have 46 chromosomes of one set of 23 chromosomes from the father and one set of 23 from their mother.
