Chromosomes from Bone Marrow of Albino Rat, Sprague-Dowley Strain

Abstract
|
|
|
A cytogenetic study having been carried out by culturing the bone marrow of the albino rat, Sprague-Dowley strain, its normal chromosome complement proved to be composed of 42 chromosomes ; 20 pairs of autosomes, and one pair of sex chromosomes, XX or XY. Twelve pairs of autosomes, number 1 through 12, and the sex chromosomes, X & Y, were acrocentrics, but the other eight pairs of autosomes, number 13 through 20, were metacentrics or submetacentrics.
Since the X chromosome was very similar to the number 2 chromosome and the Y, to the number 17, these chromosomes could hardly be clarified. The karyotype of the animal was compared and discussed with that of the Wistar-strain rat.
