Pollen-pistil incompatibility in a diploid
hybrid potato population with cultivated and wild germplasm.
ulei, we were not able to obtain chromosome counts due to the scarcity of individuals, but our results on spore sizes suggest that it might be a diploid
However, since the pollen is diploid
rather than monoploid, it
a) female worker, Ilheus, Bahia, 2n = 92; b) diploid
male, Barrolandia, Belmonte, Bahia, 2n = 92.
Several studies have demonstrated that triploid oysters exhibit higher growth rates than diploid
oysters through sterility, greater heterozygosity, and different energy allocations for growth and gametogenesis (Allen & Downing 1986, Hand & Nell 1999, Hawkins et al.
1) 91 34/short 46,XX,t(15;17)(q24; q21); 81 29/short diploid

2005b) led to a great increase in the aquaculture of triploid oysters produced by mating a tetraploid oyster with diploid
parents (Guo et al.
The researchers have developed diploid
populations with carotenoid levels generally 10 to 15 times greater than commercial tetraploid potatoes.
His whole-genome sequence (obtained from diploid
cells) has been previously sequenced to a high level of accuracy.
We have examined the effects of the naturally occurring dipeptide carnosine (beta-alanyl-L-histidine) on the growth, morphology, and life span of cultured human diploid
There are 3 types of rabies vaccine: those produced in chick embryo cell culture, which may contain egg protein, and human diploid
cell and purified verocell vaccine, both of which do not contain any egg protein.
including only samples with diploid
karyotypes for chromosomes 21,18,13, and X) and considered each autosome as a potential denominator in a ratio of counts with our chromosomes of interest.
These numbers testify to the enormous amount of research in recent years concerning this very old, very adaptable, globally-used crop, which is well-studied in part because it is diploid
and self pollinated and thus suitable for physiological and genetic research.
Normal human peripheral blood lymphocytes were used to identify the normal diploid
peak that served as reference peak for subsequent assays.
At different sites in the canyonlands there are either one or varying syntopic combinations of a triploid parthenogenetic species (Aspidoscelis neotesselata), a diploid
parthenogenetic species with two distinctive pattern classes (A.
