The document discusses the Triple X syndrome, which is caused by the presence of an extra X chromosome in females. It affects intelligence, height, speech, and behavior. Chromosome breakpoints contribute to genetic variation, as broken chromosomes can recombine in new ways during cell division, generating genetic diversity. Studies of chromosomal variations help scientists understand genetic differences between individuals and how evolution occurs on a genetic level.

4. INTRODUCTION The sciencie has allowed to advanced in the genetic knowledge. The investigation its a very importan point in this improvement. All this improvement can be use in the care of the patients and with an other studies the treatmen will be better and better.

5. TRIPLE X SYNDROME AND CAUSES.

6. WHAT IS A TRIPLE X SYNDROME? This syndrome is an abnormality in the X chromosome and for that reason it only afects women. Normally the woman have a couple of X chromosome, but in this case, they have 2 of this chromosomes.

7. WHAT IS A TRIPLE X SYNDROME? The article says very clearly that this kind of syndrome is not a heritage, it’s just a mistake in the formation of the father sperm cell or the mothers egg. It is possible too that this syndrome is only that something went wrong in the develompent of the embryo.

8. WHAT IS A TRIPLE X SYNDROME? There is no clear visual difference betwen a female with the syndrome and the other females, just in some cases they can be taller than the normal women.

9. WHAT IS A TRIPLE X SYNDROME? Intelligence may be at the lower range of normal, stature is usually tall, there may be speech and behavioral problems. The outstanding feature of the syndrome is the occurrence of twin Barr bodies in a typical cell .

10. OBSERVATION It is important to know about this syndromes, because although it does not affect a lot of women we could have one of the few ones and we have to know how to do the treatment.

11. CHROMOSOME BREAKPOINTS CONTRIBUTE TO GENETIC VARIATION.

12. CHROMOSOME BREAKPOINTS CONTRIBUTE TO GENETIC VARIATION . Chromosome regions that are prone to breakage are a rich source of genetic variation.

13. CHROMOSOME BREAKPOINTS CONTRIBUTE TO GENETIC VARIATION. The functions of this new parts are different of the others, so the chromosomal organization plays an important role.

14. CHROMOSOME BREAKPOINTS CONTRIBUTE TO GENETIC VARIATION. The new combinations begin with the “crossing over” of segments of maternal and paternal chromosomes to form hybrid chromosomes has been acknowledge as a driver of genetic variation.

15. OSERVATION The chromosome breakage in evolution has helped to confirm the importance of the chromosomal organization, because one little change can make a totally new kind. This kind of studies can help us to understand the genetic variation.

16. MEDICAL UTILITY

17. MEDICAL UTILITY The principal utility of this investigations is the the big importance in the advance of the genetic studies.

18. MEDICAL UTILITY The medicine is going to be something easier for the pacients, because with de advanced studies, is going to be more safe to do the treatments and identify the variations in the phenotype and genotype.
