How many chromosomes in a human karyotype?

Answer 1

A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryote cell. There are 46 chromosomes in a human karyotype. However, there are twenty-three pairs. In a karyotype, chromosomes are showed in pairs, because twenty-three are from one parent, and twenty-three are from another. In a cell, there are twenty-two pairs of chromosomes called autosomes, and one pair of sex chromosomes. The sex chromosomes are different in a male and a female. For a male, it is one x chromosome and one y chromosome. In a female, it is two x chromosomes. So, as a recap, there are 46 chromosomes. The only exceptions to this are autistic people. For them, there is usually a duplication or deletion of one chromosome. In other words, a person would have 47 or 45 chromosomes.

Answer 2

Somatic cells in humans contain 46 chromosomes, and they are all diploid.

Human gametes are haploid, and contain 23 chromosomes.

Answer 3

Well, we have 23 pairs of chromosomes; or 46 individual chromosomes.

Answer 4

Human muscle cells contain 23 pairs of chromosomes.
