Question

which statement best describes an understanding of genetics that would be missing without the work of mendel? the dna codes for traits would not be known. the protein codes for traits would not be known. some alleles are dominant, and some alleles are recessive. offspring receive two copies of each allele from each parent.

Explanation:

Mendel's work established the concepts of dominant and recessive alleles through his experiments on pea - plants. The discovery of DNA and protein - coding for traits came later. Offspring receive one copy of each allele from each parent.

Answer:

Some alleles are dominant, and some alleles are recessive.
