Your haplotype article is a godsend. Thank you.

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.

Haplotypes and Understanding Haplotype Networks

Okay so lamarckwaswrong asked me to help out with an issue regarding the interpretation of haplotype networks. I thought this might be a bit

It has received 41 notes.

This teaches us three things: (1) useful ≠ successful on tumblr dot com, and (2) haplotype networks are extremely unintuitive and hard to understand, and some Master's student in 2014 apparently wrote the only useful guide out there to understanding them, and (3) somehow google indexes tumblr REALLY well. Like, too well. Which would explain why i also constantly get messages asking me for permission to use photos I have rebagled.

Haplogroups

-- 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

Thanks again for the reply! I'm glad these asks aren't annoying you lol, it's so hard to find any decent information on how to keep multiple dwarf hamsters since so many sources have just defaulted to "it's too risky, idk" or insisting that they're actually solitary. Do you have a link to the study suggesting that hybridization isn't actually very common? That's another claim I've heard all the time that I've always been very skeptical of since I had read about hybrid babies having decreased fertility which makes it seem very unlikely that every single pet store Winter White/Campbells is secretly a hybrid lol, I appreciate you confirming my suspicions

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.

Decorative forms of hamsters of the genus Phodopus (Mammalia, Cricetinae): Analysis of genetic lines distribution and features of hair chang

Using a molecular genetic marker (combined sequences of the cytochrome b gene and mtDNA control region), the maternal species of the genus P

Of course it is a very small sample size, which begs the question of if its thorough enough to even count as evidence, but at minimum it shows at least SOME of our pet store campbells and winter whites do not have genetics signs of hybridization, and most outward signs are obvious to a breeder or highly experienced dwarf keeper. You'll also definitely see a huge difference in how ww and campbells interact with their families, so even if an owner accidentally buys one of each as cagemates, usually they fall out quickly or weirdly bond fantastically, I don't see much 'casual living' in cases like this, its more all or nothing, since they can't properly communicate a disagreement due to species social differences.

At some point I'll get permission from some breeders in China working on breeding out the hybridization signs from animals imported from the Philippines to show the hybrids and the work they're doing. A few breeders in the USA just imported from there as well, but we got significantly luckier with the quality of stock we got and the signs of hybridization seen in the Chinese import are not present in the new lines here, so we're hoping we avoided poorer bloodlines. We have rex/curly haired campbells dwarf hamsters in the USA now, which I cannot wait to get my hands on LOL.

Y-chromosome polymorphisms in two Pakistani ethnic groups and its relationship with neighbouring Indian populations | IJB_INNSPUB - International Journal of Biosciences || IJB - INNSPUB

By: Muhammad Tariq, Habib Ahmad, Inamullah, Umar Farooq, Tauseef Ahmad

The paternally inherited Y-chromosome short tandem repeats (Y-STRs), are excellent tool in inferring modern human evolutionary studies, genetic human identification and genetic genealogy. In the present study a total of 60unrelated male of two ethnic groups (Gujarsand Karlars) from Khyber Pakhtunkhwa province of Pakistan were analyzed using PowerPlex®12 Y-STR loci amplification system (DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 andDYS439), to investigate the genetic polymorphisms and to determine the genetic relationship of two Pakistani populations with three neighboring Indian populations of the same linguistic family.

Climate change and the decline of a foundation tree species

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…
