1
Sickle cell anemia is a genetic mutation that is actually advantageous to people living in malaria infested regions
2
Your genes will determine whether you find the chemical phenylthiocarbamide to be tasteless or bitter. This is the chemical that gives brocolli and cabbage its taste
3
We still don't know the function of more than 80% of our DNA
4
the longest living human was Jeanne Calment of France. She died at 122 years old.
5
A condition known as methemoglobinemia caused by inbreeding resulted in the Fugates, a blue skinned family from Kentucky
6
Only about 10% of cancers are due to genetics. The other 90% are typically caused by environmental factors
7
Monsanto Company has been producing seeds that become sterile after the first generation so that farmers can't replant them (yes, this has caused some outrage)
8
A genetic disease known as Laron syndrome makes you shorter, gives you a longer life expectancy, and makes you all but immune to cancer or diabetes
9
All people share a common genetic line that can be traced back to one woman who lived nearly 200,000 years ago. She has been dubbed "Mitochondrial Eve"
10
Some women have a genetic condition that makes them tetrachromatic. This means they can see 100 million colors. Most people can only see 1 million.
11
Cheetahs were nearly wiped out in the last ice age but a small population interbred and survived. For this reason, most cheetahs on Earth today are very, very close genetically
12
Blue eyed people share a common ancestor who lived about 10,000 years ago around the Black Sea
13
There is a genetic mutation that makes your bones extremely dense. One man had bones that were more than 8 times as dense as a normal human. Needless to say, he would sink like a stone whenever he tried to swim.
14
One group of 55 chimps in Africa has two times the genetic variability as all of humanity put together
15
One in every 4 million lobsters is born blue. They typically don't survive very long though.
16
Roughly half of the DNA in our GI tract has no correlation to anything (animal, plant, bacteria, etc). Scientists have labeled it "biological dark matter".
17
When scientists kept fruit flies in total darkness for 57 years, their descendants showed genetic adaptations that were useful for survival in such conditions
18
Researchers at Liverpool found that the plagues of the Middle Ages made roughly 10% of Europeans genetically resistant to HIV.
19
In Vitro Fertilization allows you to choose the sex of your child
20
When two sets of identical twins procreate with each other, their children are all siblings (genetically speaking)
21
Elizabeth Taylor's dark eyes were due to a genetic mutation that gave her double lashes
22
Scientists have recently discovered huge viruses called Pandoraviruses. A vast majority of their genes cannot be traced back to anything so some scientists have suggested creating another domain of life
23
Bananas are actually genetic hybrids. Thousands of years ago, humans crossed two strains to come up with today's tasty and sweet fruit.
24
Our bodies may not be "allowed" to live very far beyond 120 years due to genetic caps regarding how many times our cells can divide
25
