Sperm aneuploidy and diploidy rates for chromosome 13, 21, 18, X and Y were observed and recorded.
(27) Nonmolar specimens are usually characterized by biparental diploidy (1 paternal and 1 maternal chromosome complements), but some can be tetraploid.
Diploidy has been related with an increase of sperm head area and alteration in chromatin condensation in bulls [41], although in stallion sperm, nuclear area was similar between haploid and diploid sperm, but a significant difference was observed among these two subpopulations and polyploid sperm [45].
Diploidy ([lambda] = 2) (Figure 2) is the common "copy" of haploid ([n.sub.(i, ..., j)]) chromosomal complements found in most species, thus defining the diploid genotype or genome (2n or "2 x n") of a species where the total number of chromosomes is "y" so that (Equation 1): y = [SIGMA][n.sub.(i,...j)]([lambda] = 2) = 2 [n.sub.(i, ..., j)]
jirovecii typing, it did not provide evidence for or against features such as diploidy or mitochondrial heteroplasmy of P.
The HGT acinic cell carcinoma has been shown to be associated with aneuploidy, which is the appearance of distinct helioid inclusions ultrastructurally, whereas its low-grade counterpart conveys diploidy [12, 22].
Differences in stomatal and photosynthetic characteristics of five diploidy wheat species.
When single regions are being analyzed for deviation from diploidy, it becomes necessary to compare the target to reference sequences that are not expected to show variation.
In this study, it was shown that 'VNTR gen-otyping can identify the parental source of polymorphic alleles and thus discern androgenetic diploidy (homozygous and heterozygous), diandric triploidy, and biparental dip-loidy, which allows for specific diagnosis of CHMs, PHMs, and NMs, respectively.
An overall picture of the literature reveals that as many as 19 species (2 from India) of genus are chromosomally known with 7 species showing higher ploidy level than diploidy. For the origin of a polyploid series in a taxon, one of the possible reasons is the syncyte formation during meiosis [16, 17].
