Ok....here we go. I know all genetic traits are passed on from generation to generation. But what are some traits we may mistake as being genetic? for example, marking, lining manners, vocalization,non-vocalization, on/off switch. And , although training can enhance some characteristics, I do not believe training helps to a huge degree.....for example, marking.....I have had many dogs who I considered "fair" markers. These dogs passed on being "fair" markers. Now, maybe it was training program I was using, but personally I have never turned a "fair" marker into a "good" one. Just some food for thought here. PS....if you can understand this, you have a very IQ!!!
