Abstract
Diploid ox nuclei contain about 14% more DNA than nuclei from sheep of the same sex. Goat nuclei have a similar DNA content to those of sheep. In view of the similar chromosome banding patterns in these species, it appears that chromosome evolution must have involved numerous minute interstitial deletions or additions of DNA. Although chromosomes which have similar banding patterns in these three species may be regarded as homologous in this respect, and can be regarded as having a common evolutionary origin, they are not homologous for the quantity of their DNA.Keywords
