Which observation would most seriously challenge the hypothesis that most noncoding DNA is slightly deleterious?

- Species with smaller population sizes have more noncoding DNA.

- Species with larger genomes lose DNA more quickly through mutational processes than those with smaller genomes.

- There is an inverse relationship between the total amount of DNA in the genome and the percentage of the DNA that is noncoding.

- Species with larger population sizes have more noncoding DNA.

- Species with larger genomes lose DNA more slowly through mutational processes than those with larger genomes.

Tito · Answer 1

Species with larger population sizes have more noncoding DNA.

Explanation:

The statement that most non-coding DNA is deleterious contradicts the fact that Species with larger population sizes have more noncoding DNA. Had the non coding been deleterious, its proportion in species with larger population would have been less but the fact that species with larger population sizes have more noncoding DNA contradicts it.
