- The image displays a human karyotype.
- The chromosomes are arranged in pairs, ordered by size from largest (pair 1) to smallest (pair 22), followed by the sex chromosomes (X and Y).
- Each chromosome in a pair is homologous, meaning they carry genes for the same traits at the same loci, one inherited from each parent.
- The distinct banding patterns on each chromosome allow for identification of individual chromosomes and detection of structural abnormalities.
- The presence of both an X and a Y chromosome indicates this karyotype belongs to a male.
- A normal human somatic cell contains 46 chromosomes: 22 pairs of autosomes and 1 pair of sex chromosomes.
Parent Tip: Review the logic above to help your child master the concept of karyotypes worksheet.
