Every relevant pointers comes from locations of which one another W and you will Z try homozygous, therefore the pair towns which happen to be polyallelic.
grams. W try AA and Z is actually GG), they obviously didn’t inherit one place from a common ancestor.
But not, if the W and you may Z is actually homozygous within a certain area which have the same second (e.grams. one another W and you can Z was AA), they could have inherited its autosomal DNA at that location off a common predecessor.
We simply have to contrast the newest locations where one another W and you will Z is homozygous, i.elizabeth. the collectively homozygous cities.
More straight collectively homozygous towns and cities we find, a lot more likely it’s your relevant part boasts a section of DNA passed on of a common predecessor.
Lower than which simplifying presumption, having 25 % of one’s society the original couple have a tendency to comprise a few similar letters, AA, CC, GG otherwise TT; the remaining about three-residence of the people is heterozygous
To understand more about the number of choices with it, let’s imagine that brand new SNP we are considering is biallelic on the proportions p and you can 1-p of the population which have each worthy of, say A beneficial and you can C correspondingly, and you may respectively, incase liberty out of paternal and you may maternal emails, the fresh new proportions p 2 , 2p(1-p) and you may (1-p) dos of your population having per unordered few, say AA, Air-conditioning and you can CC correspondingly. „In the event the W and you will Z try homozygous during the a specific place, but with some other characters (e“ weiterlesen
