  • On your quest to find love, and

  • possibly have offspring, many of us cringe at the idea of mating with a sibling or any relative really, weird.

  • But what's the big problem with incest in the first place?

  • What actually happens when you inbreed? The first thing to understand is how any trait you have comes about. You have your

  • biological mom and your dad who each have their own unique DNA. And,

  • basically, you get half of your DNA from mom and half from dad. These DNA pairs define everything about you,

  • but in some cases, certain traits are more

  • dominant; like brown eyes for example. If your mom has two pairs of the brown eye allele, her eyes will be brown, and if your

  • dad has two pairs for the blue eyes, his will be blue as a result, you'll receive one brown gene from mom and one blue

  • gene from dad but brown eyes just happened to be a dominant trait meaning even though you get one brown and one blue from each parent, your eye color will actually be brown. It takes having two

  • recessive alleles to exhibit the other traits in this case if you got two blue alleles,

  • you'd end up having blue eyes. So what does this have to do with incest it turns out that many specific diseases,

  • or disorders, are recessive and require you to get the gene from both your mother and father.

  • They can each carry one and be perfectly healthy, making it difficult to know that they are

  • carriers. As a result, if your dad has one allele for a disorder

  • it's pretty likely that his sibling or relative probably has it too because they would have gotten it from their parents or other

  • relatives had your dad decided to mate with a random person in the population, the chance of them having the same recessive

  • gene is low, but if he chooses to copulate with his sister, or cousin,

  • then your odds of getting both of the recessive genes are much higher; still not guaranteed,

  • but much more likely. In that sense

  • It's important to remember that inbreeding doesn't create genetic mutations or defective offspring itself, but instead

  • increases the chance of a rare gene combination in fact even when both parents carry a recessive gene,

  • there's still a 75% chance that they won't both pass on the gene leading to perfectly healthy kids with respect to that particular

  • disorder or disease. So, is inbreeding ever good? Not so much in humans,

  • but we rely on it in some plants and animals; in fact different dog breeds are the result of reading?

  • relatives with similar desirable traits, like coat color, height, or snout size,

  • but we can even see the risk in dogs with many purebred suffering from hip problems,

  • eye problems, and more; while mutts or dogs with genetically diverse parents tend to be healthier.

  • Thanks for tuning in to our video, that's (that is) kind of about incest. We really hope that you enjoyed it

  • there's science in everything people. Not just kind of incest, it was fully about incest. Yeah,

  • fully about incest. If you want to watch more of our videos. We'll put some extras over here.

  • Also, make sure you subscribe to our channel, and we will see you next week for another video, peace!
