Sex Chromosomes: Since the male sex chromosomes are heteromorphic, the position of the centromere is not identical. The authors attributed this to a specific condensation process inherent in holokinetic chromosomes.

Contrary to expectations, meiotic disturbances have never been observed in any of these cases, suggesting that the question of the number of chiasmata that can be successfully resolved in autosome and sex chromosome similarities between athens in Paterson holokinetic bivalent is still unresolved.

Sex Chromosomes: Sex chromosomes determine the gender. European Journal of Entomology. In holokinetic chromosomes, a kinetochor plate to which the spindle microtubules attach covers all or the majority of the chromosome surface Wolf Until the late s, only three species were recognized in the genus Philaenus: the Holarctic P.

  • The chromosomes, apart from the sex chromosomes , are known as autosomes of an organism. The number of chromosomes varies from one organism to others.
  • During the cell division, chromatin in the nucleus shrinks to a thread like structures named chromosomes. Two major types of chromosomes can be found in eukaryotic cells.
  • The most plausible scenario of chromosomal rearrangements accompanying phylogenetic differentiation in Philaenus is advanced. Karyotype changes occurred several times independently in the genus.

In humans, there is a total of 46 chromosomes or in pair of Out of these, 2 are sex chromosome (XX or XY), and 44 are autosomes. The human male (44+XY) has 44 autosomes and one pair of heteromorphic sex chromosomes, i. e., one X chromosome and one Y chromosome. Special types of Chromosomes: Some cells at particular stage contain large nuclei with giant or large sized chromosomes.
