>The Y chromosome, unlike other chromosomes, does not undergo recombination, so it is passed down from father to son unchanged, and therefore paternal inheritance is superior to maternal inheritance. Denying this is something only PC groups do
I heard this argument, but is it true?

It depends on what you mean by “superior.” Evolutionarily speaking, no, any genetic material that does not recombine is inferior. Mitochondrial DNA is also passed down maternally without changing, and is more useful for extracting DNA from old or damaged specimens. Imo the main use of YDNA is tracing historical populations, as women traditionally left their family/clan/people to join that of their husbands.

So, what is your thinking?

alright anon ... chromosomes undergo recombination because the mother and father each have a copy of chromosome 1, chromosome 2, ... and so on.
homework question (EXTREME DIFFICULTY): how does the mother supply a Y chromosome? how many Y chromosomes does the mother have?

That's right, the claim is that since the mother has no influence on the Y chromosome and it is passed down unchanged only from the father, paternal inheritance is superior. What exactly are you being sarcastic about?

No, it just means its a good way to track linages. Sadly, people misinterpret this and that leads to haplo autism

>unlike other chromosomes
female X chromosome pairs do not recombine either. they form a mosaic instead, whereby every cell in the body of a woman exhibits only one of them randomly.

Read up on the Y chromosome. Apparently because it's not recombining like the X chromosome is, it's actually slowly getting shorter over generations.

The Y chromosome is easily the most useless chromosome. It really only counts for SRY gene (sex determine male).
It becomes progressively shorter, Basically all genes inside are non-functional. It will eventually run out, and a new chromosome will take its place, defined by SRY translocation. This is essentially sexual selection/selfish behaviour on the chromosomal level, and has occurred in other animals that do not have XY.
This post also ignores maternal mitochondria DNA, which I believe is preserved better but cannot be bothered to verify.
There is very little superior about the Y chromosome. and in aging many somatic cells will lose it entirely, with no obvious downside.
