Detailed explanation-1: -Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total. Chromosomes are made up of long strands of DNA, which contain all the body’s genes.
Detailed explanation-2: -In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females.
Detailed explanation-3: -In plants and animals (including humans), chromosomes reside in the nucleus of cells. Humans have 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY), for a total of 46.
Detailed explanation-4: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent.
Detailed explanation-5: -Human chromosomes are located inside the nucleus of the cell. A chromosome is a structure that holds your genes. Your genes determine your traits, such as eye color and blood type. The usual number of chromosomes inside every cell of your body is 46 total chromosomes, or 23 pairs.
