The Genetic Algebra of Polyploids

Proceedings of the London Mathematical Society, 1980
This paper considers the genetic algebra of polyploids for the case of \(1\) locus and \(2\) alleles and \(r\)-ploidy. The explicit structure for the \(n\)-th generation \(x_n\), is obtained. By working in a canonical basis linearisation of the quadratic transformation \(\varphi: x\to x^2\), denoting random mating, is easily effected and using the ...

Disentangling a polyploid genome

Nature Plants, 2017
The sequencing and draft assembly of the sweet potato genome has resolved much of its complex genetic redundancies, allowing a better inference of the botanical origin of the staple crop.

The Behaviour of Polyploids

Nature, 1927
MR. HUSKINS' description (NATURE, Jan. 8, p. 49) of the strict correlation he has observed between abnormal chromosome behaviour and abnormal breeding results in fatuoid oats encourages me to put forward suggestions based partly on analogous observations of my own.

Incompatibility in polyploids

Genetica, 1930
1. The theory of incompatibility in polyploids is discussed in detail, with special reference to thebehaviour of incompatibility in polyploids and the segregation of genetic types in polyploids of different constitution. 2. Cytological evidence is adduced for the tetraploid nature ofVerbascum phoeniceum.

Challenges of Genotyping Polyploid Species

2014
Most plant species are known to be either ancient or recent polyploids, containing more than one genome as a result of past interspecific hybridization events (allopolyploidy) and/or genome doubling (autopolyploidy). Genotyping in polyploid species offers a set of unique challenges.
