Some causes could be the mother smoking, drinking, doing drugs etc. Or even simply her body doesn’t fully accept the baby growing inside her so it acts out against it. Sounds strange but it happens. Also if the mother is sick with Zika or another virus, it can harm the baby’s growth.
This would be Mitosis.
Mitosis results in two diploid cells.
Meiosis, on the other hand, results in four haploid cells.
I believe the term for two similar chromosomes would be homologous chromosomes.
its a diploid cell that comes from the fusion of two haploid gametes.
aka a fertilized ovum.
