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.

Some alleles are dominant, and some alleles are recessive.

Explanation:

Gregor Mendel came up with the fundamental laws of inheritance that became the foundation of genetic research. One specific law that pertains to your question would be the Law of Dominance. The law of dominance basically, states that in an organism that has a pair of alternate forms of a gene, the trait expressed would be the dominant one.
