Gene copy number provides genomic material for diversification and gene expansions or losses

Differential gene size expansion during animal evolution (McCoy and Fire, 2020)

How do lifestyle and gene copy number correlate?


To address our research question, we fitted a custom Pagel94 model
We found that the gene copy number tends to increase in species known as pests
A custom Pagel94 model described the evolution between lifestyle and gene copy number better than the null model (\(p=0.044\))

             Gene copy number promotes the rapid             evolution of pests across Diptera
