These results may suggest that most aneuploid Yesso scallops died before the D-larvae stage, and aneuploid individuals closest to euploidy, especially diploidy
, survived longer.
Because only one chromosome is examined in this assay, diploidy
cannot be distinguished from disomy of chromosome 1.
Before therapy, FISH analysis highlighted the presence of aneuploidy, particularly diploidy
and sex chromosome disomy.
The following categories of sperm aneuploidy were included as dependent variables: disomy X (sperm FISH genotype X-X-21); disomy Y (Y-Y-21); disomy XY (X-Y-21); disomy 21 (X-21-21 or Y-21-21); overall hyperhaploidy involving chromosomes X, Y, and 21 (sum of XY, disomy X, disomy Y, and disomy 21); sex nullisomy (_21); 21 nullisomy (X_ or Y_); overall hypohaploidy involving chromosomes X, Y, and 21 (sum of sex nullisomy and 21 nullisomy); and diploidy
Colon cancers with MSI are more commonly seen in the proximal colon, have mucinous and poorly differentiated histologic appearance, with a lymphocytic infiltration, exhibit diploidy
, and most importantly, have a more favorable prognosis.
Semen analysis by electron and fluorescence microscopy in a case of partial hydatidiform mole reveals a high incidence of abnormal morphology, diploidy
, and tetraploidy.
Many people consider diploidy
to be the pinnacle of evolution," Otto says.
For example, recent data have shown that a small percentage of triploid oysters progressively revert toward diploidy
with age (Calvo et al.
The frequency of disomy XY18 and diploidy
XY18-18 recorded for the whole group in our study is within the range reported in healthy men (9,25-27).
