Hi! I have paired-end reads from corn that I mapped against the reference genome. I want to assembly the mitochondria genome, so I extracted only the reads that mapped against the mt of the reference. Before the assembly, I did a k-mer analysis of the mt reads and I got this:

Considering this is an haploid genome (mt genome), what would this mean? (My teacher told me that it seams I have two mitochondrias, and I somehow see why, but i'm not completely sure)

Also, my teacher told me to do a k-mer analysis of the unmapped reads (to the whole reference genome) and this is what I got:

I'm pretty new to this field. Sorry for the dumb questions.

Can someone tell me what does this mean?

Thanks a lot in advance :)
