Question

how did mendal explain that is possible that a trait is inherited but not expressed in an organism

Answer 1

1. When a tall plant was crossed with a short plant, the first(F1)generation plants were all tall.

2.But when the F1 generation plants were crossed, the second(F2)generation plants were not all tall ; there were both tall and short plants.

2.This shows that the F1 plants had inherited their trait from the short plants but did not express it in the presence of the tallness, and had transferred it to the next generation.

hope this helps!
cheers!! (:
