www.nationalcanineresearchcouncil.com/blog/ncrc-interview-with-dr-kristopher-irizarry/"can you explain why dogs that look alike don't act alike?" oh you mean all dogs of a breed aren't clones? duh..... BTW, I could not find any published study by this guy on the "6 genes control head size". NCRC posted yesterday "Did you know? "A surprisingly small amount of genetic material exerts a very large effect on a dog’s appearance. For example, a dog’s genome consists of 19,000 genes. According to Dr. Kristopher Irizarry, Assistant Professor of Genetics at Western University of Health Sciences, as few as six genes may determine the shape of a dog’s head, but none of those same six genes will influence behavior. A dog’s physical appearance does not predict how it will behave." I asked them for a citation to a published study on this... (not that it's the slightest bit convincing on its face: half the dogs in the world have the same "head shape")

omg, those curs at NCRC deleted my FB request that they provide a citation for the "6 genes determine head size" publication. wow. Now THAT is a sign of intellectual dishonesty. Whatever remaining respect I had for them on account of Delise's work is now totally gone.

hmmm funny neither do my kids who look alike. My one son and my husband for the most part act alike. my younger son acts more like me and Rocky acts more like my younger son. LOL

(not that it's the slightest bit convincing on its face: half the dogs in the world have the same "head shape") Over and above all the rest of the AFF wooliness, the crappiness of dog DNA tests, etc, these "genome projects" have actually ended up revealling a lot less than advertized. My current intellectual hero Rupert Sheldrake has a bet on with a genetic scientist that even for very simple organisms, even by 2029, no one will be able to predict the organism from the sequenced dna. I'm betting he'lll win. Also, be wary of ALL quantified statements about genes. We are talking many, many different things. Sociobiologists point out that we share half our genes with each parent. Then one hears that we share 98% of genetic material with chimps and bonobos. The sociobiologists are talking about genes that vary in a breeding population. When someone speaks of us sharing 98% of genes with apes, they are talking about raw counts of total genetic genetic stuff, much of which is fixed. We share some fixed genes with inselct and jellyfish. Also, to say "six genes control head shape", are we talking six loci, each of which could allow for two to many, many different alleles? I suspect so. But the bottom line here is that some aspects of gross form may enable or inhibit this or that behavior, but behaviors are determined by other things, including other genes. That's been known forever. I guess AFF just got the memo. |

I look forward to learning much here
