To clarify, how does the process in which humans inherit particular traits differ from the process in which plants inherit particular traits?

I'm not sure exactly what you are asking with this, but there are several examples of differences, too many to really encapsulate in an answer here. In corn, for example, there is the process of double fertilization in which two sperm fertilize the endosperm and one fertilizes the embryo, so that the nutrient tissue of the seed is triploid, containing 3 sets of chromosomes, 2 from the male and 1 from the female. However, the embryo, which actually gives rise to the plant still is diploid and contains one set from male and one from female.
Plants can "self" which means the male part of the plant can fertilize the female plant and so you have less genetic variation. Plants can also asexually reproduce where there is literally no genetic variation as a shoot forms from a root forming a new plant. Plants also can become tetraploid containing 4 sets of chromosomes.
So there are a few differences anyway, in that humans are just diploid, sexually reproduced, and contain sex chromosomes that differentiate female from male. Most plants contain both parts and have the same chromosomes in both parts.

Well, Humans (cro-magnon) are one of the worlds most complicated species. There is no such thing as the IQ of a plant, and scienctists are not sure if that is inherited. Most important, plants do not have genders, meaning there are no x and y chromosomes. That means that sex-linked diseases and traits cannot occur.

Plants allow inheritance to simply happen.
With humans there's always lots of Lawyers and Court time involved (look at Ana Nicole Smith âº)

When there is sexual reproduction in the plants, there are basically no differences.
