Triploidy is a chromosomal abnormality caused by an additional haploid set
The nuclear division is meiotic in which sets of chromosomes are reduced (generally from two sets to one) and results in four nuclei each containing a haploid set
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).
All the functions of each diploid somatic cell, therefore, are genetically encoded twice, once per haploid set
Telophase I--each pole of the cell has a haploid set
of chromosomes and cytokinesis occurs.
Along the axis of the double helix, the distance between two successive nucleotide is approximately one third of a nanometre (nm), so the total filament of human DNA is about 3 ft (1 m) long and divided among the 23 chromosomes of each haploid set
andersonii has suggested that it is a natural Tripsacum-Zea hybrid carrying 54 Tripsacum chromosomes (2n = 3x = 54) and a haploid set
(n = 10) of Zea chromosomes (Levings et al.
rossius chromosomes divide to produce both a degenerating and a persisting haploid set
of autodiads (hemiclone).
65), all chromosomes of the haploid set
were classified as metacentric, their arm ratios ranging from 1.
In mammals, genome diversification occurs in germline during the specialised division (meiosis) in gametes, when chromosomes recombine and assort into new haploid sets
as they are passed from parent to offspring.
5-7) Apart from rare hereditary cases, complete hydatidiform mole (CHM) has a diploid nuclear genome that comprises paternal DNA ("diandry") exclusively; the 2 paternal haploid sets
may be derived from duplication of the DNA content of a single sperm or, less commonly, from the DNA of 2 separate sperm.
e) a human ovum or an ovum of a non-human life form that otherwise contains haploid sets
of chromosomes from both a human being and a nonhuman life form.
