Whats interesting to me is that along with the autosomes (chr1-22) the sperm contributes either an X or Y sex chromosome. The X chromosome is large and carries a lot of important genes. The Y chromosome on the other-hand is much smaller and carries very few functional genes (primarily just SRY).
So If you think about it girls get ~5% more genetic material from their father than boys.
- throwawaymaths 1y ago2.5% (but not really, also remember the chromosomes have different sizes). this is probably why distribution of traits in men has fatter tails than in women.
- grumpy-de-sre 1y agoI 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.
