height is controlled by thousands of genes each of which provides a small effect, and the relationships between those genes are non-trivial. i don't think concepts from mendelian inheritence (like recessive) are super-meaningful in cases like this.
- eru 3y agoBtw, doesn't Mendelian inheritance only really work for species with two copies of each chromosome? Lots of plants have many more copies. I guess Mendel got lucky that he investigated plants that were simple enough. (And from what I've read, his research assistants actually cheated him: the numbers he got were too close to the theoretical averages, the variances were much smaller than math would predict. His assistants made the numbers come out like the boss expected them.)
