Principal components analysis shows that some karyological characters as number of subtelocentric and acrocentric chromosomes seem to be important and explain most of the total variation among the taxa.
The chromosomes of Liliaceae have diversity in size, number and structure, but the chromosome numbers of Fritillaria are larger and more stable than other genera (Peruzzi et al.
In the last stage of the generation, the roulette wheel selection with elitist approach determines the pop_size chromosomes in PO[P.sub.t][union][O.sub.t] to be used in the next generation.
Gains of chromosomes 7, 17 and loss of chromosome Y have been described as characteristic of papillary renal neoplasms,[sup.12] and only very rare tumours were reported to lack these marker changes.[sup.13] The centromeric probes identified none of the characteristic chromosomal changes, in keeping with their lower incidence in type 2 papillary RCC.[sup.14]
The Orthoptera in early cytogenetics: Mendel's principles and big chromosomes.--The history of cytogenetics will be forever intimately associated with the Orthoptera.
Allelic losses of chromosomes 9, 11, and 17 in human bladder cancer.

Apart from chromosome 5, ETV6 has also been found to fuse with other genes in different chromosomes like AML1 in acute lymphoblastic leukemia (ALL), with ABL or JAK2 in early pre-B-cell ALL, with MN1 in MPD, with MDS1/EVI1 in MPD, and with STL in a B-cell ALL cell line [7].
To improve the genetic diversity of wheat germplasm, mapping of the wheat chromosomes is utmost necessary.
Nineteen bivalents were observed in pollen mother cells (PMCs) in most cases suggesting that [A.sup.r]/[A.sup.n] and [C.sup.c]/[C.sup.n] chromosomes paired well in the new-typed B.
This study found suggestive evidence for genes influencing susceptibility to alcoholism on chromosomes 1 and 7 as well as weaker evidence for a gene on chromosome 2.
Although telomeres are generally considered to be localized structures at the ends of chromosomes, such sequences are also being identified at internal positions in chromosomes [4].
