Chromosome Set

Chromosome Set

 

the complement of chromosomes in the nucleus of any plant or animal cell. The number of chromosomes in a chromosome set is constant for every biological species; the chromosomes are of a specific size and have distinctive morphological characteristics.

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.
Thus, it appears that in triploids rather than a whole haploid chromosome set (haplome) being silenced, regulatory mechanisms involve selective individual gene-copy silencing [21].
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.
From these polar bodies in the cytoplasm protein fibers form which correctly distribute the duplicated chromosome set to the newly forming daughter cells.
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.
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.
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.
Because they will later fuse with the female sex cell, or egg, the pollen grains (like the egg) contain only half the chromosome set and are thus easier to count than other cells, which contain the double set.
