polüploidsuse
Polüploidsus is a condition in which an organism has more than two sets of chromosomes. This is in contrast to diploids, which have two sets, and haploids, which have one set. Polüploids can be either polyploid or autopolyploid. Polyploids are organisms that have gained extra sets of chromosomes from different species, while autopolyploids have gained extra sets from the same species. Polüploidsus can occur naturally or be induced artificially. It is a common phenomenon in plants, where it can lead to increased size, vigor, and sometimes new traits. In animals, polüploidsus is less common and often results in developmental abnormalities. The study of polüploidsus is important in fields such as genetics, evolutionary biology, and agriculture.
