I thought the genetics one was well written, It gave me some good information - mainly that in the long run, there are so many factors involved in the genetics, that the percentage difference that is contributed by the pod or pollen parent for specific traits is almost equal. In this article the discussion centered on scape height & flower size.
Actually, if one is too confused, the first part of the article talks about the genetic components - yes, confusing.The second part goes into the whys & hows of outside factors influencing genetic differences & how scientists try to decrease those outside factors.
The third part was the learning part for me - sections 1 & 2 were just background.
The author analyzed the AHS registration diploid database and ran statistical programs. What he determined is that both the pod & pollen parent influenced the flower size and scape height equally. He gave an example of a 4 inch flower crossed with a 6 inch flower. if 4 x 6 - the average seedling flower size was 5.11 inches. if 6 x 4 - the average seedling flower size was 5.09 inches - not statistically different.
Apparently these differences can rarely be determine with qualitative traits such as flower color - because that trait can't be measured.
I didn't understand the first couple of genetics articles, but this one I did. Now I am going to have to reread those previous articles. ~Jan
