I couldn't be assed to do the math, not just chromosome size but also number of genes etc, get's tricky to quantify.

Fascinating to think about the variability introduced by having only a single copy of the X chromosome. Lot's of interesting genes in there, MAOA/MAOB (primary neurotransmitter breakdown pathways), AR (androgen receptor), OPN1LW/OPN1MW (red green color blindness), G6PD, etc.
