The world population is very likely to drop to one before it could increase to three. Genetic defect problems solved. For how difficult living without electricity can be for those without the right knowledge, see the movie Hunger Games or the TV show Walking Dead.

Human genetics started with a black diaper. Around 1900, the English doctor Archibald Garrod began studying cases of alkaptonuria, a disorder that turns people’s urine black when exposed to air. Garrod noticed clusters of alkaptonuria in certain families, and assumed something in their environment or diet caused it. Then, in 1901, a mother brought in her newborn baby, whose diapers looked like an octopus had used them. Garrod realized that someone so young had almost certainly inherited alkaptonuria. Further digging revealed that the child’s parents were first cousins. Certain he was onto something—but unsure of what—Garrod published his findings. He soon got a letter from English biologist William Bateson.

The year before, three biologists had rediscovered Gregor Mendel. Mendel, a monk, had uncovered the first hints of genes (in pea plants) in the 1860s, but had died unappreciated—better known for his showdowns with local sheriffs than his science. Bateson had not been among the trio to rediscover Mendel, but he made up for that by becoming the most zealous “Mendelist” in Europe. He preached the monk’s doctrines tirelessly, and even took up cigars and chess because Mendel liked them.

Bateson’s letter explained to Garrod that alkaptonuria fit the pattern for recessive genetic disorders, which are caused by inheriting two defective copies of a gene. . . .

You seem to be asking whether we think it would be okay for that to happen.

They either breed (or clone themselves) or homo sapiens becomes extinct.

Consider that you had two parents. Your spouse had two parents. There are you and your spouse (2) and Parents (4). But your parents and your spouse's parents had two parents each as well. That's 16 people. Do the math and it doesn't take long to realize that, especially if family lines are from the same origin (ie: anglo saxon), that somewhere, someone has married into the family.

Mathematically, someone is married to a relation every 13 generations. Not exactly close relations, but the person is related.

Considering just parents and one offspring - at 13 generations (based upon 25 years/generation) you have ~12,000 relatives with about ~9000 still alive. At 20 generations, that's ~1.5 million relatives and ~1 million still alive in about 500 years. At 40 generations (1000 years) that's about a trillion ancestors still alive and ~1.5 trillion ancestors in total.

Whoops! Not a trillion people on the earth and we know that not too many families are just 1 child. North America and Europe are generally about 2.3 children now with larger numbers in the past. So where are the extra people?

Well, if you could identify every single person in your family tree, you would find any number of ancestors, and as close as a few few hundred years ago, would show up time and time again in the family tree. So there has been a touch of inbreeding. The mathematics involved makes it obvious that we are all the products of inbreeding.

The good news? I'm happy to report that you are related to Royalty, somewhere along the family tree.

Wars, famine, disease, genocide. All of the above.

Well, from what I know, according to Mendel's law of inheritance, recessive genes come out dominantly of a mated pair one every four offspring, so that one child is going to show recessive genetic traits as 'dominant.' I've actually seen this in a family where both parents are dark haired, eyed, and skinned, but, on each side (unrelated), there was a light haired parent or grandparent. They had exactly four children, 3 girls and 1 boy, and the boy was light skinned and eyed. The 3 girls were all dark haired and such. Isn't that interesting?
