|Joseph: So if recombination is limited deterioration is inevitable?|
But wait males also have an X, therefor that X should also show signs of deterioration.
The X-chromosome in a male comes from his mother. X-chromosomes recombine in mothers. (It's believed that sex chromosomes evolved to progressively restrict recombination between male and female chromosomes, a result of clustering of male advantageous traits.)
|Joseph: Therefor if a man has a son, who then has a son, who then also has a son, we should be able to see some X chromosome deterioration somewhere along that patrilineage in at least some of the gametes.|
The father does not pass his X-chromosome down to his son. A son acquires his X-chromosome from his mother—who just happens to have two recombining X-chromosomes.
Exactly. The dumbass has now been straightened out.
