That’s some flawless enunciation.

If the wizarding gene is dominant, as J.K. Rowling says in her famous series of Harry Potter books, then how can a wizard be born to muggle parents (non-magical people)? And how can there be squibs (non-magical people born into wizarding lines)?
It seems these baffling genetic questions have finally been answered, thanks to Andrea Klenotiz, a biology student at the University of Delaware.
In a six-page paper, which she sent to Rowling, Klenotiz outlines how the wizarding gene works and even explains why some witches and wizards are more powerful than others.
“Magical ability could be explained by a single autosomal dominant gene if it is caused by an expansion of trinucleotide repeats with non-Mendelian ratios of inheritance,” Klenotiz explains.
What does this mean?
In school we learn the fundamentals of genetics by studying Gregory Mendel’s pea plant experiments and completing basic Punnett squares. Basically, we’re taught that whenever one copy of a gene linked to a dominant trait is present, then the offspring will exhibit that dominant trait, regardless of the other gene.
However, Non-Mendelian genes don’t follow this rule, which is the basis of Klenotiz’s argument. She says that the wizarding gene could be explained if it’s caused by a trinucleotide repeat, which is the repetition of three nucleotides — the building blocks of DNA — multiple times.
These repeats can be found in normal genes, but sometimes many more copies of this repeated code can appear in genes than is standard, causing a mutation. This kind of mutation is responsible for genetic diseases like Huntington’s Disease. Depending upon how many of these repeats occur in the genes, a person could exhibit no symptoms, could have a mild form of the disease or could have a severe form of it.
In her paper, Klenotiz argues that eggs with high levels of these repeats are more likely to be fertilized, a phenomenon known as transmission ratio distortion. She also suggests that the egg or sperm with high levels of repeats is less likely to be created or to survive in the wizarding womb.
This argument answers several questions about wizarding genetics:
How can a wizard be born to muggle parents?
Genetic mutations can randomly appear, meaning anyone could be born with the wizarding gene. However, there’s a better chance of magical offspring occurring if the parents are on the high side of the normal range for mutations.
How can a squib be born to wizard parents?
Although parents with these mutated magical genes would be likely to pass the gene on to their children, there’s still a possibility that any given offspring might not inherit the trinucleotide repeat.
How can varying degrees of magical ability be explained?
The more repeats a wizard inherits, the stronger the magical power he or she will have. If both wizarding parents are powerful wizards, it’s likely their offspring will also be powerful.

Far and away one of the nerdiest things I’ve ever read. Love it.

Members of Congress are living off food stamps for a week to protest Republican cuts. It’s a challenge for them, but GOP cuts would hurt millions of everyday Americans.

A hearty ‘fuck you’ to all the cis women out here on that “I don’t want a trans woman in the bathroom because of penises” bullshit.
Because we don’t fucking do genital checks at the fucking door.
And the only reason you have this mentality is because you hold on to the bullshit notion that you can “TELL” what a trans woman looks like based on dehumanizing stereotypes.

I just really want to start a gym for geeks where you’d have to like run away from Daleks or GET TO ENGINEERING through some ducts or like compete in a Tri-Wizard Tournament or train with lightsabers and it would just be hilarious nerdy wonderful fun.

Mirha-Soliel Ross: Why she kicks ass
- She is a vegan transgender video maker, performer, sex worker and animal rights activist who has produced over a dozen videos which have been screened at festivals internationally, since 1992.
- As an activist, she worked from 1997-1999 with the staff at the 519 Community Centre to develop Meal-Trans, Toronto’s first publicly funded, multi-services program for low income and street active transsexual and transgender people.
- In 1997, she created Counting Past 2, a multi-disciplinary art festival dedicated to the promotion of work produced by local and international transsexual and transgender artists, and from 1996 to 2001, she hosted ANIMAL VOICES, a weekly animal rights radio show.
- She has been the recipient of several grants from the Canada Council for the Arts and her video, Mateřština (co-directed with Mark Karbusicky), won the Marian McMahon Award at the 2004 Images Festival in Toronto.

recently i learned that crows and ravens have a baffling habit of sneaking up on other animals and pulling on their tails
the behavior seems to be relatively universal among various species of crows and ravens across the world
they seem to do it with anything they can find that has a tail, ranging from something as small and harmless as squirrels to something as large and deadly as eagles
i have absolutely no idea what their motives are, other than to be mischievous and cute
The world’s worst enemy could just be the corporate executive, blindly doing what he does for the good of the short term personal profit. He buys the souls of our government to feed his appetite for more power and money. He lies, cheats, steels, and does whatever he can do to maximize his own bottom line.
The reason why he could be our worst enemy is that he is the only one in the above lineup who, without doubt, exists.
