  • To further study the roles of partial AZFc deletions in spermatogenic impairment and the relationship between complete and partial AZFc deletions, we typed these deletions, did quantitative analysis of DAZ gene copies, and performed Y chromosome haplogrouping in seven pedigrees of complete AZFc deletion carriers, 296 infertile and 280 healthy men in Chinese.

  • spatial
  • In particular, females with Turner's syndrome (TS) who have only one X-chromosome exhibit deficits of spatial ability whereas males with Klinefelter's syndrome (KS) who possess a supernumerary X-chromosome are delayed in acquiring words. (ox.ac.uk)

  • probably
  • The Y-chromosome is an extreme outlier compared to modern groups, probably because of its heavy G2a domination, whereas the mtDNA from Treilles appears just like a normal and unexceptional Mediterranean-type population. (blogspot.nl)
  • On the contrary, the length of the W chromosome can fluctuate over short time scales, probably involving both shortening and elongation of non-coding regions. (royalsocietypublishing.org)
