Experiment 2: the reemergence of traits |
|
Mendel used true breeding strains that express one or the other of a pairs of traits. These pairs of traits were determined by crossing true-breeding parents, and looking at the offspring, which are known as the first "filial" or F1 generation. He called traits that were visible in F1 plants dominant, those that disappeared where known as recessive. Now we have new questions to answer: are the factors responsible for recessive traits still present in F1 organisms? To answer this question, we will start (as always) with two parental (P) lines: one expresses the dominant and the other the recessive trait. |
