Image shows karyotype of a female. Her somatic cell has a diploid number of 46.
refer to your chapter 5 note.
What is diploid number & haploid number of chromosome?
1. Diploid - organisms or cells that have 2 sets of chromosomes.
2. Haploid - cells that have only one set of chromosomes.

Here are some images which are related to cell division:
1. Image below shows the chromosomes, DNA, histone proteins inside the nucleus of a typical cell.
2. Image below shows chromosomes.
- When the chromosome condense, coil-up and tighten during prophase of mitosis (or prophase I or prohase II of meiosis), the chromosome appear as two identical chromatids called sister chromatids attached together at the contromere.
3. Prophase I of meiosis I.
- At the chiasma, exchange of genetic material between the non-sister chromatids of bivalent through the process of crossing over.
- Crossing over results in new combination of genetic material and is important source of genetic variation.
