Question

4. One reason that parents in many cultures have for centuries asked that their children marry their "own kind" was the belief that the material basis of inheritance was fluid (BLENDINGTHEORY). Marriage outside their own kind would adulterate the purity of the blood lines. Mendel's experiments refuted this fluid based theory of inheritance.(Not all parents know this.)
The critical observation in Mendel's work which led to the rejection of BLENDING THEORY was a. chromosome condensation b. reappearrance of the recessive phenotype in the F2
c. anaphase I pairing d. mitosis e. enteleky

Explanation / Answer

B. Reappearance of the recessive phenotype in the F2 Mendel worked with the pea plants to determine if Blending Theory was applicable. He was never able to actually view a chromosome, mitosis, DNA etc. so A,C, and D are not the answers. I don't know what enteleky is, I guess typo. Reappearance of the recessive phenotype in the F2 showed that genes did not blend with one another but preserved.
