Eli5 how inbreeding causes the offspring have a higher change if developing genetic disorders
In: 18
**DNA is like an instruction manual** for how your body should be built and run.
**You inherit one full set of instructions from your mom and one full set from your dad**. So you actually have two versions / copies of each page of the instruction manual. So as long as one of those versions is good ans readable, you have no problem building the thing. If your dad’s page 6 is torn or ripped out or smudged, you can use your mom’s copy.
Here’s the problem: **If your parents are related, they have a bigger chance of both having the same damage on the same pages of their instruction manuals**. That increases the chances that there will be a page you can’t read in either set of instructions, so you’re screwed. In this analogy, that’s a genetic disorder. When you get the same defective gene copy from both parents. In can still randomly happen with non-related parents, but it’s more likely if they are.
