CHROMOSOME STUDIES ON HETEROSEXUAL TWINS IN CATTLE : IV LONG-TERM OBSERVATIONS OF SEX-CHROMOSOME CHIMERA RATIO IN CULTURED LEUKOCYTES
スポンサーリンク
概要
- 論文の詳細を見る
Sex-chromosome chimera ratio in cultured leukocytes was examined regularly during 1～15 months after birth on 7 heterosexual twins involving the freemartin. All freemartins and male co-twins showed 2A-XX/2A-XY chimerism. The chimera ratio varied in each animal, but between co-twined pairs, the difference of the ratio was insignificant. In addition, no significant difference was detected in the chimera ratio in each individual throughout the observation periods (1～15 months). This suggests that the sex-chromosome chimerism may be of an invariable nature for life.
