Pedigree Query

Per this article http://www.circledhorses.com/The%20X-Factor.htm Winning Colors' heart was measured and was found to be large. Her sire, Caro, had a normal sized heart - his was measured during autopsy. Another Haun article. Is there any source of hard data? I would love to see a histogram of male ...

... Not really, because her heart is still smaller than that of a heterozygous mare who is expressing the large heart gene. As an example, Winning Colors was heterozygous for the large heart gene because Halo didn't have it, but she did express the large heart gene. Was there a measurement of heart...

LOL! But I'm a bit confused re. "third cell to the left in cell division 4". I took the meaning to be roughly "some cell in the early-stage embryo". Chosen by the guy with the clipboard. :) I think there would need to be a single cell source for the developing heart. If it were truly a mosaic, you ...

First ignore the top side of the pedigree because your colt got the Y from his sire, making him a colt. The only place the X can come from is the dam side. I know, I only mentioned the sire because of your comment about the ideal cross being good blood and speed and conformation on the top and an X...

Hi PZ, I sent you an email. Thanks for the info about X inactivation, and interesting that the equine genome has been sequenced. I remember reading something about a geneticist at the University of Kentucky that was working with Haun on identifying the X-factor gene. I'm no expert in this area, but ...

Hi xfactor fan. I was hoping you'd chime in here. I understand the basics of x-factor inheritance. The new wrinkle for me is the part about mares with 2 x-factor genes only expressing one of them because one X chromosome is inactivated. That must have come out since I had genetics, back in the Dark ...

Thank you, PZ. So the strength of Epic Win's performance indicates that both he and his dam are x-factor carriers. Does this mean that all of Epic Win's daughters will now show up as x-factor mares? And that in turn answers my unasked question about the x-factor data in the database. Some of it is "...

Hello Everybody, I'm new here and I apologize if this question has been asked before. I'm interested in the pedigree of a horse named Epic Win, specifically whether he could have had the large heart gene. In his pedigree http://www.pedigreequery.com/epic+win ...the x-factor trace seems to stop after...
