I don't specifically remember that exchange, but I probably brought it up; it's an example I often use.
Does your family's experience mean that the gene(s) for no wisdom teeth is (are) dominant? That would weed the trait out even quicker.
I am not really up on genetics...so I dont know if the gene(s), for no wisdom teeth is(are)dominant or recessive...but if a dominant trait, then indeed, that would weed out the trait even quicker...I was just glad that both my boys, like their dad, had no wisdom teeth...
I remember when my husband, myself, my older son, and my younger son, all had to take a blood test for compatibility with my older son...my husband, my younger son, and my older son all tested out at being blood type O+...I however tested out as being A+...I remember the doc telling me that I had to have an O+ gene for blood type, but O+ was always recessive compared to A+...so we could figure that I had a gene for A+ blood and also a gene for O+ blood...but both my sons obviously received an O+ gene from their dad,(as he was already blood type O+)and in both instances, they received the O+ gene from me, rather than the A+ gene...it was a 50-50 random shot as to which gene they would get from me, and it proved to be a case of 100percent of my children getting the recessive gene from me...
That is the one time I got a little lesson in genetics from a doctor...it found it very interesting...
