taking the swim test is just as terrifying as jumping out of a plane without a parachute

I promise you, swim tests are not as bad as they seem on paper. Assuming you’ve practiced, you will do just fine! They are just there to psych you out :)

Ditto! I was entirely convinced I was going to completely bomb my swim test, but I ended up being the best out of my group for the test :) And for ours you have to tow people too!

After I finished I was just like…”Well. That was easier than expected”…lol.

*!URGENT*! Pit Bull to be euthanized if he can’t be re-very soon! Cody was involved in a dog dog fight after the door was left open accidentally, when the neighbor tried to break it up he bit her. The owners father now wants the dog to be euthanized if he can’t be rehomed immediately. Cody is located near Chicago, Illinois. Please help give Cody a new start in life! If you want to help Cody please contact his owner at 262-689-5873.

No offence but this dog has attacked another dog and has bitten a person. This dog should not be going to just any home that will take him to save him from being killed.
Honestly I don’t blame the owners father for wanting the dog put down. You should’t have to worry about accidentally leaving your door open and having your dog rip out and go attack another dog. On the same verse, no person should have to worry about their neighbours dog attempting to kill their own dog and then biting them.
This is obviously an animal with aggression issues that needs to be placed somewhere equipped to deal with that.

With my biology background, I’m surprised I didn’t realize this sooner…

If Nalani were to give birth to a calf, assuming she’s not related to the father of her calf, the offspring wouldn’t be affected by inbreeding at all.

You receive half of your chromosomes from your mom and half from your dad. Because Nalani and her father were both Katina’s calves, Nalani likely has a few pairs of chromosomes that are identical to each other. This is when inbreeding becomes a problem, because harmful, recessive genes are more likely to be expressed when two chromosomes are exactly the same.

However, if she mated with an unrelated male, she would only pass down one set of chromosomes to her offspring, not both. If Nalani has a pair of chromosomes in her cells that contain harmful recessive genes due to inbreeding, it wouldn’t affect the calf because it wouldn’t be getting both pairs of chromosomes from her.

So, if Nalani becomes pregnant at any point in the future, I don’t want to see people complaining about the calf being inbred, lol (unless, of course, the father of the calf is related to Nalani.) And this goes for Adan and Keijo as well, if they ever have offspring.

I’m a bit confused, maybe I’m just not understanding something here. The chromosomes an individual passes down to their offspring are most likely a mix of the father and the mother’s, right? It’s not like we only inherit our grandfather or our grandmother’s DNA, if that were the case we could technically be genetic siblings with our uncles/ aunts. So isn’t it the overwhelming possibility that Nalani’s calf will inherit identical genes from both Taku and Katina? 

That being said I don’t believe this level of inbreeding in this situation is cause for major concern. Should Nalani breed with an unrelated male, chances are the calf will be perfectly healthy. 

Well not quite. Inbreeding can only occur if the two individuals are actually related. If two individuals are inbred, but un-related, the offspring are indeed not inbred. Granted the more inbred something is the greater the chance of them having reproductive issues that give them a hard time is. For instance, Giant otters used to be extremely in-bred in captivty (to the point where no pups were surviving more than a few days past birth), and once fresh animals were imported, those once failing animals started to produce healthy, vivacious pups.

Or if you want, you can refer to this coefficient of inbreeding chart, which shows that even if Nalani bred with Keijo, the calf would still be a healthy outcrossed animal with a 0% COI

Yes, yes, and yes !!
