1. The introduction was all about X and Y chromosomes in embryology, and I fell asleep.

2. The results suggest that the Y chromosome heterochromatin appears to have a modifying effect on the phenotypic relationship between morphophysiological traits during human ontogenesis.

4. The Y chromosome is to yield other intriguing tales as well.

5. Here we present the Y chromosome data of 1,652 individuals from 47 populations of Mon-Khmer(MK) and Hmong-Mien(HM), which distribute primarily across Southeast Asia and extend into East Asia.

6. The AZFc region on human Y chromosome has been found to be functionally important in spermatogenesis.

7. In this study, we compared the Y chromosome diversity of the Peninsular Daic to those of Chinese Daic and the Mon-Khmer populations to reveal the origin of the Peninsular Daic populations.

8. The positive rate of Y chromosome of mice in Groups 2 - 6 was 100 %.

9. Conclusion Micro-deletion in AZF gene of Y chromosome is one of the major risks for oligospermatism and azoospermatism.

10. That's because the male Y chromosome comes equipped with a so - called sex determination gene called SRY.

11. Objective : To investigate the clinical effect of Y chromosome polymorphism.

12. Y chromosome has two types of polymorphism : metacentric ( or submetacentric ) and acrocentric chromosomes.

13. The Y chromosome is starting to yield other intriguing tales as well.

14. Methods: Both karyotypic analysis and Y chromosome were performed in 107 blood specimen from azoospermic men.

15. Like humans, platypuses carry an X and a Y chromosome.

16. New, still unpublished work reveals that the Neandertal Y chromosome differs from the human one.

17. Objective: To investigate the relativities of long Y chromosome and clinical effects, including infaust pregnancy, gonadal dysgenesis and sex reversal syndrome.

18. Objective:To explore the relationship between Y chromosome microdeletion and non-idiopathic infertility in male cases with dyszoospermia.

19. Objective:To investigate the relativities of long Y chromosome and clinical effects, including infaust pregnancy, gonadal dysgenesis and sex reversal syndrome, etc.

20. Conclusions:The long Y chromosome may be related to some clinical effects such as infaust pregnancy, gonadal dysgenesis and sex reversal syndrome.

21. If the imperfections of the "Y chromosome" result in death, then male offspring will not be produced.

22. In man, for instance, the genes that control gender are on the Y chromosome.

22. try its best to gather and build good sentences.

23. Consequently, a Cain gene on an X chromosome can safety kill the Y chromosome and not risk suicide.
