Add a definition Secondly, not all polyploids have a diploid relative available in nature and genetic analyses of these polyploids must be carried out in thepolyploidform. From theCambridge English Corpus Also, because polyploidization events were considered rare, polyploids may have a single origin and, thus, high genetic uniformity is maintained across different individuals. From theCambridge English Corpus A chromosome bin map of 16 000 expressed sequence tag loci and distribution of genes among the three genomes ofpolyploidwheat. From theCambridge English Corpus Still, it has to be realized that in allopolyploid species and species with apolyploidorigin, homeology across the genome may impede such conclusions. From theCambridge English Corpus In addition,polyploidforms of plants can adapt to more extreme conditions than their diploid relatives and are thus of great practical value. From theCambridge English Corpus There is a strong emphasis on cytogenetics throughout; whilst this is certainly important inpolyploidcereals, its role in diploids is over-played. From theCambridge English Corpus One advantage ofpolyploidmapping over diploid mapping comes from the increased chance of sampling a non-homozygous parent. From theCambridge English Corpus This will in turn provide insight into the studies of the parentage formation and genome constitution ofpolyploidspecies. From theCambridge English Corpus Many new species have been produced in connection with tetraploids and higher polyploids. From theCambridge English Corpus Of these, 27 (82%) were diploid, 3 (9%) were mixoploid and 3 (9%) werepolyploid. From theCambridge English Corpus Most odd-number polyploids are practically sterile because meiosis divides by 2, leaving a remainder of single chromosomes for random distribution. From theCambridge English Corpus The detection and estimation of linkage in polyploids using single-dose restriction fragments. From theCambridge English Corpus The percentage of aneuploid cells was 10.2 and 10.6% of cells werepolyploid. From theCambridge English Corpus However, all except one of thesepolyploidcells arose from either multipronucleate zygotes or embryos which had been exposed to toxic culture conditions. From theCambridge English Corpus Construction of linkage maps in polyploids is more challenging than that in diploids due to the complex nature of multiple alleles in polyploids. From theCambridge English Corpus 106 polyploids is as convenient as that in diploids. From theCambridge English Corpus Therefore, many studies on constructing linkage maps have focused on diploid relatives of polyploids, such as in potato and alfalfa. From theCambridge English Corpus Song et al. (1995) detected extensive changes in the nuclear genome of synthetic polyploids in each of the first five generations.
