How To Use polyploid In A Sentence
- We also investigated a possible DMSO effect on the frequency of polyploid and endo-reduplicated cells by chromosome counting.
- By analyzing DNA sequences of two single-copy nuclear genes and the genomic AFLP data, we assess the allopolyploid origin of A. collina-4x from ancestors corresponding to A. setacea-2x and A. asplenifolia-2x, and the ongoing backcross introgression between these diploid progenitor and tetraploid progeny lineages.

- He was lucky to have chosen traits in his plants that are governed by such genotypic interactions by luck; if he'd observed phenotypes influenced by polyploidy he would probably have concluded that 'god did it.' Full Text Of Obama's Big Race Speech: A Big Break With Political Precedent
- The comparison of newly formed polyploids with their haploid progenitors has revealed that nascent polyploids have a defect in stationary-phase viability.
- Furthermore, apomictic reproduction has been found in most polyploid Corollinae species, which, if transferred to cultivated beet, has the potential to improve the fixation of desired genotypes in breeding programmes.
- Feed crop breeding by polyploidy can enlarge the plant cellular size, so the plant has the thick and high stem, thick blade , and increases the content of protein, carbohydrate, vitamins and minerals.
- Analyses of the age distribution of duplicate genes in diverse flowering plants indicate that essentially all may be paleopolyploids, but this should not be equated with the polyploid speciation rate.
- a polyploid cell
- There is, however, evidence of genome downsizing in polyploids relative to their diploid progenitors in some cases.
- Different from bivalent polyploids, multivalent polyploids pair their chromosomes among more than two homologous copies at meiosis.
