Detailed explanation-1: -Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total.
Detailed explanation-2: -Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
Detailed explanation-3: -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-4: -Diploid. A diploid cell has two complete sets of chromosomes. Most cells in humans are diploid, comprising 23 chromosome pairs, so 46 chromosomes in total.
Detailed explanation-5: -In a diploid human cell, chromosome number is 46.
