These share morphology and lack of p57 expression with typical androgenetic CHMs, but the DNA genotyping result of biparental diploidy
could be misinterpreted as a nonmolar conception in the absence of correlation with morphologic features and p57 results.
These results suggest that female triploid Yesso scallops can release mature and functional gametes, and aneuploid progeny closest to euploidy, especially diploidy
, survive longer.
Evidence for diploidy
at the adenine phosphoribosyltransferase locus.
Multicolor fluorescence in situ hybridization analysis of aneuploidy and diploidy
frequencies in 225,846 sperm from 10 normal men.
Egg maturation and parthenogenetic recovery of diploidy
in the scorpion Liocheles australasiae (Fabricius) (Scorpions, Ischnuridae).
The original breeding objectives and recombination patterns of the parental genomes dictated that this work be started at the tetraploid level but the requirements of turfgrass breeding demand diploidy
. In a single experiment, a large number of diploids were obtained from the selected best tetraploid clones available.
Polyploid oysters can lose chromosomes de novo and can even revert from triploidy to diploidy
or from tetraploidy to triploidy (Allen et al., 1997).
However, recent data show that a small percentage of triploid individuals progressively revert toward diploidy
, introducing the possibility that Suminoe oysters might establish self-sustaining populations.
These associations usually publish quarterly bulletins dispensing practical, and sometimes scientific data which covers a range of topics from gardening tips, memories of travelling and botanising trips, hybridising techniques and the inherent diploidy
and triploidy factors, seed germination and a variety of humorous personal trivia.
People, parrots, perch, polyps, and all the animals ia between usually inherit one copy of a set of chromosomes from each of their parents, a system called diploidy
Since (assuming a 1:1 primary sex ratio) the production of females is associated with production of an equal number of males, the fitness benefit from each brood doubles, thus canceling the diploidy
Most multicellular organisms have diploidy
, and it is thought that this maintains population diversity and improves the survival of species in a fluctuating environment.
