[Genome] pseudo autosomal regions in cow genome

[Kayla Smith]

Dear João,

The cow assembly has chrX but not chrY, so even if the cow chromosomes 
have a PAR, bosTau3 doesn't.

But yes, the PAR is a mammalian thing, so cows have it too.

If you google "cow pseudoautosomal region" the first match is a
commentary on an article that used genomic alignments to look at the
boundary of the region in a bunch of mammals, concluding that it had
moved "fairly recently" in mammalian evolution (~26-70Mya).

I hope this information is helpful to you.  Please don't hesitate to 
contact us again if you require further assistance.
