According to our research of Texas and other state lists there were 16 registered sex offenders living in 79347 zip code as of September 02, 2017. The ratio of number of residents in zip code 79347 to the number of sex offenders is 481 to 1. The number of registered sex offenders compared to the number of residents in this zip code is near the state average.
A Barr body (named after discoverer Murray Barr) is the inactive X chromosome in a female somatic cell, rendered inactive in a process called lyonization, in those species in which sex is determined by the presence of the Y (including humans) or W chromosome rather than the diploidy of the X or Z.eft: DAPI stained female human fibroblast with Barr body (arrow). Right: histone macroH2A1 staining. Arrow points to sex chromatin in DAPI-stained cell nucleus, and to the corresponding sex chromatin site in the histone macroH2A1-staining.
So, from my studies I know that Barr-bodies are not totally inactive, they, in fact, do have some very limited transcriptional activity. It might be low in intensity, but still vital? I'm just guessing. My other guess is linked to the development of a Barr-body in a cell with two active XX chromosomes early during fetal development.
