Is there a reason why incestuous couples produce deformed offspring?

As much details as possible please, and does this also occur in animals?Is there a reason why incestuous couples produce deformed offspring?
actually it doesn't usually express til a couple generations down the line








Most people have odd recessive disorders hidden in their coding. If you mate with your sister, well she also has similar DNA, and a high chance of also having that rare recessive disorder. Two recessives mean the disease expresses itself, and what do you know, your child is born with laser vision.





If you mate with someone with differing genes, it's a very very low chance they'll have your same recessive disorders, so their Dominant trait causes you to not pass on your horrible curse.








It happens exactly the same in animals, their DNA is no different from ours in what it's made of. Breeding programs have to trade with other zoos because they want to ensure genetic diversity (for pandas and cheetahs, etc)Is there a reason why incestuous couples produce deformed offspring?
Genetics, whether it's in a human, an animal, a fish or a plant, can make deformities. Inbreeding causes traits that probably wouldn't show up in a child to be more likely. Some genes have to be carried by both parents to become a trait in a child. It doesn't necessarily happen every time, but it's far more likely in a child whose parents have very close genetic makeups, such as a brother and sister since the same two parents made them.





For instance, I have a cousin who didn't realize until after he and his wife had three children together that they both had a recessive gene that caused Batten Disease. If only one had been a carrier, it wouldn't be passed on. As it was, their oldest developed symptoms about the time their youngest was learning to walk. All three of their boys died. Luckily my cousin's two sisters married men who didn't have the gene. If my cousin had had an incestuous relationship with one of his sisters, their child would have had Batten Disease as well because they both were carriers.





Incestuous relationships in animals are what produces the particular breeds. Breeders of a cat, for instance, will often add the same male with traits they want to enhance in the line multiple times to get a certain outcome. Say there's a tom cat that's got a very unique eye color that the breeder thinks will be marketable, he/she will mate the tom with his daughter, his daughter's kittens that show signs of the trait will have kittens who will also be bred to the same tom or half-siblings that show the trait. Along the way, there will be deformed kittens born that got defective genetic combinations from the in-breeding.
It's actually easier to explain with animals.





Inbreeding is responsible for how there are different ';breeds'; of dog, even though they are all the same species. You start be breeding together two dogs that have the same characteristic- say, a pushed-in snout. And eventually, the children of those dogs will have more of that feature, or set of features. Smaller, bigger, whatever. It's the progressive elimination of certain genes.





We do it on purpose to get specific desired traits, but as a result, we lose good traits, and gain mutations too. Purebred dogs are more prone to some types of illness than mutts, because of various defects that are not easy to understand, and weaker immune systems. Some of those bred-in traits, like the pushed-in snout, are like defects, and can make them less functional.





All physical traits, like the shape and size of your nose, or your hair or eye color, are controlled by genetics. Hair color is relatively simple, and blonde hair is what's called a ';pure recessive'; trait. Both of your parents need to have the gene for it in order for you to get it, although either of them could have the gene and not know it. If they both had the same parents, then they would be more likely to both have the same gene, and you would then be more likely to get it.





So, when people inbreed, many traits that they only have half of, in the form of one side of a pure-recessive trait, can be passed on. Any ';expressed'; (present outwardly) recessive traits are passed on. Including, often, defective genes, such as extra fingers.





In real life, it's not all that likely that a child of incest will inherently be born with gross defects. It's a statistically good chance, and it would be a real problem over the course of generations, which is why there are laws against it, but the individual child isn't likely to be horribly malformed. Just a somewhat greater chance of undesired genetic traits.
It's gods way of telling you ';even though your cousin looks hot to you'; You should never decide to fornicate with her ...for the master of the skies shall strike you down for this and cause the birth of a mutant child be the result.


Awww comon guys...am I right or am I right? What's with all the downers.....it's true!!!!
I dont really know alot about this but animals donesnt count, but people arent suppose to because the genes are so close that they produce deformed kids.
