Morphologically,species A is very similar to four other species,B-E.Yet the nucleotide sequence deep within an intron in a gene shared by all five of these eukaryotic species is quite different in species A compared to that of the other four species when we study the nucleotides present at each position.
-Which of the following items does not necessarily exist in a simple linear relationship with the number of gene-duplication events when placed as the label on the vertical axis of the following graph?

Question

Phenotypic complexity is not directly proportional to the number of gene-duplication events, as differences in gene regulation and expression patterns can result in vast differences in phenotype despite similar genomic content. The other options (number of genes, number of DNA base pairs, genome size, mass of DNA) are all generally expected to increase proportionally with the number of gene-duplication events.
