Mendelian Inheritance

One of the major criticisms against Mendelian laws is that they do not recognise that

  1. A.one trait is often controlled by many pairs of genes
  2. B.single factor inheritance is never a reality
  3. C.complete dominance is always possible
  4. D.incomplete dominance is not possible
  5. E.hybrids exist in living organisms
Show the answer and explanation

Answer: A (one trait is often controlled by many pairs of genes)

Explanation

Mendel studied one gene per trait, but many traits (e.g. height in man) are controlled by many genes.
