#haplotypes

I think to this day it is the single most often-used thing I ever posted on tumblr. I frequently have people telling me they used it, or it was helpful to them.

the internet is heckin' weird.

It has received 41 notes.

-- humans can be divided into about 100 haplogroups

-- each haplogroup is made up of a mixture of haplotypes

-- haplotypes share substitutions that define the haplogroup

-- defining substitutions enable the evolutionary relationships between haplogroups to be worked out

-- can be pictured as a network

-- empty nodes represent haplogroups that are unknown in the human population

-- all human haplogroups can be linked in a single network

-- age of a haplogroup can be linked in a single network

SORRY NEW MED ALMOST KILLED ME BUT IM BACK!!!

First off here's the study I was referring to, its from 2013 but they pulled phodopus species from pet stores in SE Asia, Europe, and North American pet stores and tested their haplotypes, finding that there was no evidence of hybridization in a small sample from these locations.

Climate change and the decline of a foundation tree species

A worldwide increase in tree decline and mortality has been linked to climate change, and where these represent foundation species this can have important implications for ecosystem functions. Dalmaris et al. undertake phylogeographic analyses across the species range of Eucalyptus wandoo, an endemic tree of south-western Australia, and find that a combination of phylogeography and…
