Im trying to explain to a guy that does pass on the antler genetics. He cant wrap his mind around that and I remember you have posted some research on that. Any help is greatly appreciated!
 
^^^ What he said. Both parents are contributors to their offspring's DNA, including the antler-coding genes.

No different in people and sex linked traits. Men pass on a gene that influences breast size in their female offspring, just like the mother does.
 
Baldness in humans tends to be passed thru the mother's genetics. My mom's dad was as bald as a ping pong ball. All the men on my dad's side of the family kept their hair. I'm now sporting a western haircut: a lot of wide open spaces! Thanks a lot, Poppa!
 
Actually my understanding is bucks get antler genetics from their mother.
Lets say a twelve pointer breeds a doe and the doe has a buck fawn. That buck fawn will have the antler genes of the father of his mother, not the twelve pointer that bred his mom.

Many examples exist of sex-linked traits. In essence, traits that are only carried on the X or Y chromosome. If it is on the X chromosome, a male can only get that trait from his mother, as he had to get the Y chromosome from his father. Examples of sex-linked traits in humans are red-green colorblindness, male-pattern baldness, hemophilia, and Duchenne Muscular Dystrophy. Although the genetics of antlers in bucks is still little understood, and is clearly VERY complex, there is strong indication the general shape and configuration of the antlers are passed from mother to son. In a review of parentage for deer at the Univ. of Georgia research facility, where the parentage of many generations of deer is known for certain, it was found that male offspring of individual bucks did not produce antlers that looked anything like their father's antlers. Not in size, shape, configuration, etc. All of a single buck's male offspring would have very different antlers. Yet when looking at all of the male offspring of a given doe, those bucks DID produce antlers that were similar in shape and configuration. This STRONGLY suggests mothers are passing on the major genetic components of antler shape/configuration to their male offspring, while fathers are not. Now this doesn't mean males don't pass on ANY genetic antler information. A few deer breeders who appear to have figured out more about heritable antler traits than is available in the scientific literature are still selectively breeding particular bucks to pass on specific traits, but the basic-frame of antler shape and point configuration appears to be passed from mother to son.
 
I'll see if I can find it, but I was watching something Dr. Grant Woods was doing and he read off a new study that came out stating that 65-70% of a buck's antler genetics came from their mother.

So do you think a doe would pass antler genetic code along to female offspring thus continuing the antler trait in that lineage of does?
 
So....with mothers passing on the major genetic components of antler shape/configuration to their male offspring....I wonder where the mother gets the genetic components? From her father?.....I ask because every time we've killed a nice buck off of the property I've often wondered if, or hoped that, his genes have been passed on....so would it be doe fawns we should hope the nice buck fathers? (crazy question I know)...and not that we can control any of that...just interesting to discuss and think about.

Yes. In fact, many bucks leave their birth range and disperse sometimes great distances to establish an adult range. If antler shape was primarily passed down from fathers, they would take those traits with them when they leave. However, have you ever noticed how a given location keeps producing the same shape rack year after year, often for decades? In fact, sometimes specific locations become "famous" in hunting circles for a particular antler trait. Why does that trait keep showing up in the same locations over many years? Because it is being passed on the X chromosome down to many of the females in the population, and female social groups do not disperse from their birth range anywhere near as frequently or as far as bucks do.

A buck will have an X and a Y chromosome. He had to get the X from his mother. He has to then give that same X to his daughters. So, he carries that antler genetics with him, and passes it to his offspring, but only to his daughters.

So the history of 6 point bucks on my farm is being passed down by the females.

That is a real possibility, as long as food resources aren't a major problem.

I've seen areas where an incredibly high percentage of the local bucks don't grow browtines. That is unquestionably a genetic trait.
 
For about the first 10 years we had our place, the majority of bucks would not have a left browtine. Over the years of hammering the does (for no other reason than just wanting the meat), we unintentionally created a doe sink, where does from surrounding areas filled in "the gap" on our place that could now support more deer. Again, it was unintentional, but we now have some really great traits and unique antler characteristics we believe came from those does in the surrounding areas.

I think this happened on our place too. We killed a lot of does for several years, and at the same time, most bucks would have a long beam on one side, maybe one tine, and a normal rack on the other. Most didn't have brow tines. At first I thought it was injury related, but we saw it way too much for that.

My guess is now, that does with different genetics moved in, and we only occasionally see those same funky racks.

This is the best example of the 6 pointer to date but several have been nice deer that I am happy to kill but they only have the brow times and one point up on the main beam. We used to think that we could kill enough 6 point bucks and get rid of the trait but not quiet so easy.

But what about yearling buck dispersal? Shouldn't they be seeing everyone else's buck fawn genetics?
