2017年10月5日 · Autopolyploidy: An autopolyploid cell does not undergo meiosis since it has arisen from one parent. Allopolyploidy: An allopolyploid cell can undergo meiosis. Examples. Autopolyploidy: Autopolyploidy is seen in crops such as wheat, oats, sugar-cane, potato, peanut, banana, and coffee.

多倍体的形成有2种方式，一种是本身由于某种未知的原因而使染色体复制之后，细胞不随之分裂，结果细胞中染色体成倍增加，从而形成 同源多倍体 （autopolyploid）；另一种是由不同物种杂交产生的多倍体，称为 异源多倍体 （allopolyploid）。

2010年3月3日 · Biogeographic and ecological surveys point to an association between the formation of autopolyploid lineages and environmental change. We thus hypothesize that polysomic inheritance may provide a short-term evolutionary advantage for autopolyploids compared to diploid relatives when environmental change enforces range shifts.

Autoallopolyploids are hexaploids or higher ploidies that combine the processes of auto- and allopolyploid formation, as for example when an allopolyploid forms by hybridization and then undergoes a within-species (i.e., autopolyploid) duplication.

2021年8月16日 · The cell or organisms in autopolyploid condition is called an autopolyploid. Natural autopolyploids are Tolmiea menzisii (piggyback plant) and Acipenser transmontanum (white sturgeon). In agricultural setting, autopolyploidy (particularly, autotriploidy) is applied in producing seedlessness in watermelon and bananas.

term autopolyploid is commonly used; when the copies come from different species, then the term allopolyploid is commonly used. Polyploid species are all around us: crops such as bread wheat, coffee, potato, rapeseed, oats, banana, kiwifruit, strawberries, and sugarcane are all unarguably polyploid (see e.g., Renny‐Byfield and Wendel, 2014 ...

2024年3月4日 · Polysomic inheritance is a feature of arguably the best-characterized naturally occurring autopolyploid species, Arabidopsis arenosa, for which a great deal is now known about the evolution and genetic mechanisms underlying restoration of “stable” meiosis following the transition from diploid to autopolyploid populations (Bomblies and ...

同源多倍体（autopolyploids） 指增加的染色体组来自同一物种，一般是由二倍体的染色体直接加倍产生的。同一物种经过染色体加倍形成的多倍体，称为同源多倍体。同源多倍体在植物界是比较常见的。由于大多数植物是雌雄同株的，两性配子可能有同时发生异常减数分裂的机会，使配子中 …

Our results suggest that observations of polysomic inheritance can lead to relabeling of taxonomically allopolyploid species as autopolyploid and highlight the need for further cytogenetic and genomic investigation into polyploid origins and inheritance types.

Autopolyploid individuals apparently arise more frequently in natural populations than do allopolyploids, but autopolyploids that persist are rare. However, many autopolyploids may go undetected because they tend to be less morphologically divergent …
