What is the result of autoploidy occurring from meiosis?

In the process of autoploidy, an organism has an increase in chromosome number due to the duplication of its own genome, which typically occurs during meiosis. This can happen when a failure in meiosis leads to a diploid gamete instead of the normal haploid gamete. When two diploid gametes combine, they can form a tetraploid zygote since each contributes the full diploid set of chromosomes (2n).

Additionally, if a triploid organism, which may arise from the fusion of a haploid gamete with a diploid gamete, is involved, triploid zygotes can also be produced, as they contain three sets of chromosomes (which can come from various combinations of diploid and haploid gametes). Thus, both triploid and tetraploid zygotes can emerge from the process of autoploidy, reflecting the variability and complexity of chromosomal outcomes following meiosis in certain situations.
