FAQ
Frequently Asked Questions
It produces gametes (sex cells) with the same chromosome number as the parent cell, rather than the reduced (haploid) number.
No. Mitosis is normal somatic cell division producing identical diploid cells. Ameiosis is a faulty version of meiosis, the specialized division for gamete production.
It is occasionally observed in certain plants, fungi, and rarely in animal species, often linked to hybridization or genetic mutations.
In some contexts, like apomixis in plants, ameiosis can be beneficial by enabling clonal reproduction via seeds, preserving successful genomes.
