Should You Research Y-DNA Pseudoautosomal Regions? | Genetic Genealogy

Does the y-DNA chromosome have recombination points that create DNA segments? If there are segments, can you research them?

Thanks Andy!

[@FamilyHistoryFanatics]

You bet!

[@behunin1963]

So do are sudos what cause the male Y to mutate? My thoughts are you get 2Y or 1Y sudos from dad, sorry girls it just is, and then a guy gets X from mom. Does the missing sudo get back filled from the X chromo or does it stay blank? Either of which could contribute to mutation.

Segments? Are they referring to genetic materials?

[@PC-lu3zf]

I thought they were non in the Y as it’s excluded from 23 and me plus Gedmatch

[@FamilyHistoryFanatics]

Correct, they don't show you anything on the Y. You would have to look at those segments manually. (Sounds like a science project for me and my brothers)

What about double cousins.My family has a few

[@FamilyHistoryFanatics]

I have some videos on Double cousins

My daughter got my Y-Chromsome and a couple of my nieces got their father as well. The statement that females don't inherit the Y-Chromosome is incorrect,

[@lawilks1]

@@gruilen I have t disagree with this statement as they did not know that she was my daughter until they compared her DNA with my DNA. But let's just say you're right, my nieces also have their father Y-Chromosome. Now before respond to this just know that one of my niece's fathers has not done his DNA so how could she have it if 23andme just out it in? If 23andme just fills it in why don't they do it for all of them?

[@FamilyHistoryFanatics]

23andMe will display a Y haplogroup for females if there is another DNA kit that is identified as a brother or father through DNA. You can know this by looking at the chromosome painter and seeing whether 1 X is painted (male) or 2 X are painted (female). Also in the browser, if you compare yourself to your daughter, then the X chromosome should show a half match across the entire chromosome.

X chromosome I’ve lots of matches

[@FamilyHistoryFanatics]

Awesome.

I wrote 1st comment! ( my 1st ever!) ;) ok more jokes Why ask y-DNA? I got one more.. Andy Please tell us about y-DNA BUT PLEASE don't go 'man-splain'in' the X chromosome! :)
