Autoriploidy: Fertility and Phenotypic Effects

In this article we will discuss about:- 1. Origin and Occurrence of Triploids 2. Chromosome Pairing and Chiasma Formation in Auto-Triploids 3. Fertility of Auto-Triploids 4. Pneotypic Effects of Auto-Triploidy. Origin and Occurrence of Triploids: (i) Triploids originate from hybridization between auto-tetraploids (4x) and diploids (2x). The autotetraploid produces diploid (2a) gametes which when fertilized by a normal monoploid (x) [...]

Autotetraploids: Origin and Chromosome Pairing | Euploidy

In this article we will discuss about:- 1. Origin and Occurrence of Autotetraploids 2. Chromosome Pairing and Chiasma Formation in Autotetraploids 3. Fertility 4. Genetics. Origin and Occurrence of Autotetraploids: Autotetraploids originate both spontaneously and can be experimentally induced; the various means of their origin are briefly described below: A. Spontaneous origin: (1) In diploid (2x) plants, sometimes a tetraploid [...]
