What would a karyotype like this look like after meiosis?How did the organism get these chromosomes, and where did they come from?

If you looked at a karyotype of a germ cell - egg or sperm cell - you would see only 1 of each chromosome in a karyotype, not two!!! Germ cells have only half the number of chromosomes as a diploid cell one of each pair. The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis.

Karyotypes are like representations to indicate the number of chromosomes of a particular organism.

The karyotype shown after meiosis will be left with just 23 single chromosomes (not in pairs). They are haploid cells.

In meiosis I , all the chromosomes replicate and the homologous chromosomes then separate afterwards.
Then in meiosis II, the chromosomes are the separated by their centromeres giving rise to 4 cells with 23 single chromosomes (haploid cells).

The organism got this karyotype from the contribution of the both parents nuclei (haploid egg cell and haploid sperm cell) fusing to give rise to a cell with diploid chromosomes.
