Which statement best describes an understanding of genetics that would be missing without the work of Mendel?

A. DNA codes for traits would not be known.
B. Protein codes for traits would not be known.
C. Some alleles are dominant, and some alleles are recessive.
D. Offspring receive two copies of each allele from each parent.



Answer :

Final answer:

Mendel's work with alleles showed how dominant and recessive traits are inherited and the concept of independent assortment during meiosis.


Explanation:

Alleles are different versions of a gene, and they can be dominant or recessive. Mendel's experiments showed that traits are inherited in pairs of alleles, where dominant alleles mask recessive ones. Understanding that genes segregate independently during meiosis was a key concept introduced by Mendel.
