A karyotype is a picture of all of the chromosomes present in a single one of your cells. A karyotype is a test used to check for chromosomal abnormalities. A karyotype can tell how many chromosomes a person has, as well as detect any errors those chromosomes may have. Normally, a person has 46 chromosomes or 23 pairs.
Twenty-two of the paired chromosomes are similar in males and females and are called autosomes. In the female, the twenty-third pair consists of two X chromosomes. In the male, the twenty-third pair consists of one X chromosome and one Y chromosome. A karyotype is a pictorial representation of an individual's chromosomes. Cell division and chromosome duplication. The fertilized egg, or zygote, begins as one cell containing forty-six chromosomes, and the number of cells increases by mitosis, a process of cell division that produces new cells containing duplicates of all forty-six chromosomes. The gametes are formed by a process of cell division called meiosis.
