Question

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

a. The DNA codes for traits would not be known.
b. The 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 1

C. Some alleles are dominant, and some alleles are recessive.

Step-by-step explanation:

Answer 2

The answer is c. Some alleles are dominant, and some alleles are recessive.

Gregor Mendel established the principles of heredity. To explain his experiments and discoveries, he invented terms dominant and recessive in reference to traits.

The other statements are not true because the DNA and protein codes were researched and discovered almost a century after Mendel's work. The statement that offspring receive two copies of each allele from each parent cannot be true since offspring receive only one copy of each allele.
