ZFX and ZFY

I took the sequence-part of ZFX and ZFY that NCBI - National Center for Biotechnology Information - has of the spieces below and compared them with man and aligned them.ZFY showed a good gradual change. The numbers are in percent similarity.Man — 90,9 - Dog
Man — 91,4 - Ring-tailed lemur
Man — 96,7 — Siamang
Man — 96,7 — Agile gibbon
Man — 98,0 — Orangutan
Man — 99,2 — Gorilla
Man — 99,5 — ChimpanzeeZFX showed a slower mutation rate than ZFY.Man — 95,7 - Hund
Man — 96,7 - Katta
Man — 99,7 — Hylobates agilis
Man — 99,7 — Siamang
Man — 99,7 — Orangutang
Man — 99,7 — GorillaThis might be very well known to all of you. Would this mean that ZFX produces a good working protein and are very sensitive for changes and that zink finger proteins from y-chromosomes of these spieces hardly work or doesnt work or are switched off, just because they have changed faster?And what is the creation explanation for this.

Some translations.ZFX showed a slower mutation rate than ZFY.Man — 95,7 - Dog
Man — 96,7 - Ring-tailed lemur
Man — 99,7 — Hylobates agilis
Man — 99,7 — Siamang
Man — 99,7 — Orangutan
Man — 99,7 — Gorilla

This topic seems to be a continuation of the now closed "No mutations in neutral gene-parts?" at http://EvC Forum: No mutations in neutral gene-parts?Currently, Convince-me has started 5 topics (see http://http://www.evcforum.net/cgi-bin/membermsglist.cgi?action=...), with seemingly a fair amount of overlap between them.I fear that Convince-me is showing signs of becoming a bit of a version of a "Peter Borger" type poster (albeit with a clearer defined content).Convince-me, I suggest that you take care in maintaining a focus, and not spread the same ideas over too many topics.This message is NOT intended to be a disciplanary warning (ie. There is no suspension pending); Just an effort to head off what seems to be a potential problem.I may be wrong.Adminnemooseusps: Convince-me, I actually do like your messages, but please consider the above suggestions.------------------

Ok, I will keep to this topic. The reason I started a new topic was to get attention for my question. If no one answers that question I will get information about this on other sites.

As far as I can see from the literature, the main reason is theorised to be that the Y linked gene mutates more rapidly because more mutations are produced in males given the continuous production of sperm. I havent seen anything to suggest that the ZFY protein is substantially less effective.For references seeLori-Jayne Lawson , Godfrey M. Hewitt
