how did you get whites from that pairing?? i don’t understand genetics plz help

mad-hare:

lol that’s okay! The whites are albinos, so they have two copies of an otherwise recessive gene. I was surprised too because we got none the first litter and neither of the parents have a white ancestor minus one great grandparent.

So since both parents carried a copy of the gene (50% chance to inherit) which needs two copies it gives a kit a 25% chance of being born albino..

Here we see the convergence of genetics and statistics! You can predict how things will go, but sometimes statistics goes “ha, nah, have a batch of 4 kits where 3 display a trait that’s a ¼ chance”.

today i found out that when monarch butterflies migrate south for the winter, all the ones that go across the middle of lake superior suddenly stop going south and go west for five miles and then continue south. which really freaked scientists out cos like What is in the Middle of Lake Superior what do Butterflies know that We Dont Is This The End Times etc. anyway turns out about a hundred million years ago there was a mountain there and the butterflies still think they gotta fly around it. classic butterflies

combine this with the fact that caterpillars literally turn into bug soup in their crystallis, meaning there is no central nervous system to carry over any information, but they seem to retain memories from caterpillar life regardless…

and it brings up a lot of questions about what kind of information can even be stored in genes, like… does genetic memory really exist? what does this mean for humankind? could a race of people develop an instinctual memory of the land like this? are there people whose bones tell the stories of ancient mountains? what about my people? is the diaspora something that can be felt among every one of us? are we all the living cumulation of hundreds of thousands of ghosts?

i am simultaneously fascinated and frightened by this. classic butterflies indeed

#i’ve always been afraid of butterflies #i knew those fuckers were shady #what do you know butterflies #what the fuck do you KNOW

Isn’t this why we’re instinctually afraid of spiders? We’re not taught, we just know.

It’s thought that some people have genetic memories that carry over a fear of things. My friend and her mother are deathly afraid of snakes, and my friend’s grandfather on that side nearly died from a snake bite when he was a little boy. 

That may also explain why certain things, like spiders and snakes, tend to frighten people. Something about the movement, in particular, seems to be what bothers people. Enough bad experiences stack up. 

It’s not everyone, though. I don’t mind snakes at all, they aren’t creepy to me, and I know people who feel the same about spiders. When I was a little kid, I liked spiders ‘till someone yelled at me for handling one, and now I’m arachnophobic. (don’t yell at little kids about how spiders are “deadly dangerous”.)

Some of it may also be accidentally taught. Most representations of spiders and snakes in media are extremely uncomplimentary. 

Also, rodents. Mice and rats. People seem to be afraid of mice pretty frequently, but those aren’t dangerous at all. 

On a related subject, there’s a theory about that phase kids go through where they insist there are monsters in the dark. Part of it is probably because tiny child brains don’t like the darkness (can’t see what’s in it, things look weird) and they decide “there’s monsters” to explain the fear, but it’s thought to partly be an ancestral memory of when there were monsters. For a long time in human history, the area outside the firelight, outside the cave or the house, did have monsters, in the shape of predators. 

Not that it matter but don’t these people realize that kids who are half white can come out looking completely like their white parents. Like my grandpa is an Afro- Latino and my mom looks completely like her mother whose mostly white. I don’t understand why race mixing matters anyway 🤷🏻‍♀️people love who they love.

Because they’re stupid

My favorite examples of how crazy genetics can be is with twins 

I love genetics. Biology is a trip

This is always so cool.

All people with blue eyes can be traced
back to one person who lived near the
Black Sea less than 10,000 years ago. Source Source 2

Now when I see a person with blue eyes, I’ll know they’re a descendant of Ocean-Eyed Slut Man.

You leave great grandpa ocean-eyed slut man alone, he was just living his life

Actually, since this was determined using mitochondrial DNA, the ocean-eyed slut would be a woman, not a man. Mitochondrial DNA is passed down by mothers.

Gram-gram knew how to party

dear ocean eyed party gram-gram thank u for spreading your weird eye mutation and giving every fanfic writer a reason to know an unholy amount of synonyms for the word ‘blue’.

@dak-legacy ur a mutant

Look! Him pants!!

who told him its ok to match neutrals 

JONAH GOT PANTS! Good for you Jonah. Next week we’ll work on shoes

why are you two always so critical of his choices 😦

How does that even….

Genetics are weird.

Oh, this isn’t genetics! c: Jonah had a pretty major leg surgery a few months back—a FHO, or femoral head ostectomy.

For a while, he looked like this:

Now his pants are coming in nicely!

(unless u mean his coat pattern.  That’s all genetics.)

OHHH, I see it now!

For a minute I thought he just had fur that changed color/pattern right on his hindquarters. Buh, I have no brain.

Poor baby, I hope he gets well soon!

‘no brain’, NO WAY. 

Comments like yours are legit some of my favorite because I get to talk about COOL COAT PATTERNS IN CATS.  There are cases where shaving a cat has resulted in a drastic coat pattern change.

SAY HELLO TO QUATTRO

Before he was shaved, his fur was pretty typical siamese: all creamy with just his legs, face, and tail dark. But now his whole flank is dark.

Why?

Because Siamese points are actually a result of temperature-dependent albinism! 😀 Also known as
acromelanism, this is a neat little mutation in which a specific enzyme (tyrosinase, which is responsible for melanin production) stops functioning at a normal body temperature, but will function when it gets cooler.  So in cool zones on a cat’s body (face, ears, tail, feets), melanin production is normal.  The warm zones develop in a lovely cream.

Since his butt is cold, it has normal melanin production.  Once it gets all fuzzy and starts a typical shed pattern, it’ll come in cream eventually.  Until then, he’ll have weird pants.

Genetics are weird and AWESOME.

It got even better

Wait so what about the first cat? We’re his pants always that different to his jacket or are his new pants different to his old ones??

Jonah’s pants are just slow growing. His pants look different bc they’re still growing in.

What a beautiful post
