Question $2(1$ point$)$

You are sequencing the metagenome of a simple bacterial community with two species. The two species are present in the community in equal numbers. Species A has a $9$ Mb genome, Species B has a $1$ Mb genome. You produce $100$ Mb of shotgun sequence data. What proportion of the shotgun sequencing reads will come from each species?

$75\%$ from Species A and $25\%$ from Species B

$50\%$ from Species A and $50\%$ from Species B

$90\%$ from Species A and $10\%$ from Species B

$10\%$ from Species A and $90\%$ from Species B
