The number of C-bands in the A chromosome set
were detected to determine whether the variation of this structure can account for numerical polymorphism for Bs.

Ecologists and fish specialists from Europe, New Zealand, and the US detail the natural history and genetics of common carp and the origin, variation, and genetics of Japanese ornamental koi carp; aquaculture and nutrition aspects, including those related to carp in Europe and Asia, reproduction and first feeding, chromosome set
manipulation, sex control, and gene transfer, and traditional feeding and replacement of fish meal; diseases and immune response; feeding ecology, carp as an invasive species, and recreational fishing for carp and its implications for the management and growth of carp populations; and the effects of pesticides and natural toxins.
It was calculated the mean values for the total haploid chromosome set
(THCL), the longest (L) and the shortest (L) chromosome absolute ([micro]m) and relative (%) length, as well as the average chromosome length per haploid set ([chi]chrom) and the ratio of the longest to shortest chromosomes (L/S).
Thus, the increase of mean chiasma frequency produced by the Spanish supernumerary segment, located interstitially on chromosome S11, is both inter- and intrachromosomal, whereas in the Austrian population, where the segment is located very close to the centromere, its influence only affects other members of the chromosome set
, i.e., it is entirely interchromosomal.
From these polar bodies in the cytoplasm protein fibers form which correctly distribute the duplicated chromosome set
to the newly forming daughter cells.
"This research is the first system which is able to look at the genetic and environmental influence, which is a key issue when looking into infertility." In the technique developed at Newcastle, stem cells with XY chromosomes (male) were developed into germline stem cells which were then prompted to complete meiosis - cell division with halving of the chromosome set
. These were shown to produce fully mature, functional sperm called scientifically, In Vitro Derived sperm (IVD sperm).
We then discuss the idea that if parts of the chromosome set
were deleted, parts of our bodies may not be able to respond as needed in an emergency.
manipulation and sex control in common carp: a review.
Overall, caffeine was a risk factor when the fetal karyotype (the full chromosome set
of the nucleus of the cell) was normal but not when the karyotype was abnormal.
Thus, it appears that in triploids rather than a whole haploid chromosome set
(haplome) being silenced, regulatory mechanisms involve selective individual gene-copy silencing .
giganteum has genomes M (the larger chromosomes set) and T (the smaller chromosome set
), derived from F.
