Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population (alleles), a situation called polymorphism. No two humans are genetically identical. Alleles occur at different frequencies in different human populations.
Do all humans have the same genetics?
Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each persons unique physical features.
Are humans 99% genetically identical?
All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases. There are also people who smoke, never exercise, eat unhealthy foods and live to be 100. Genomics may hold the key to understanding these differences.
Are humans genetically closest to?
This will allow us to look for the genetic basis of what makes modern humans different from both bonobos and chimpanzees. Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
What race was the first human?
The San people of southern Africa, who have lived as hunter-gatherers for thousands of years, are likely to be the oldest population of humans on Earth, according to the biggest and most detailed analysis of African DNA.
What are the 5 races of humans?
The revised standards contain five minimum categories for race: American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Other Pacific Islander, and White.
Which race has the most genetic diseases?
Examples of genetic conditions that are more common in particular ethnic groups are sickle cell disease, which is more common in people of African, African American, or Mediterranean heritage; and Tay-Sachs disease, which is more likely to occur among people of Ashkenazi (eastern and central European) Jewish or French
Can two humans have the same DNA?
Based on an examination of our DNA, any two human beings are 99.9 percent identical. The genetic differences between different groups of human beings are similarly minute.
Who is stronger a chimp or a human?
Chimpanzees do have stronger muscles than us – but they are not nearly as powerful as many people think. This result matches well with the few tests that have been done, which suggest that when it comes to pulling and jumping, chimps are about 1.5 times as strong as humans relative to their body mass.
What animal is most like humans?
The chimpanzee and bonobo are humans closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule thats the instruction manual for building each species.
Who was first man in the world?
ADAM1 ADAM1 was the first man. There are two stories of his creation. The first tells that God created man in his image, male and female together (Genesis 1: 27), and Adam is not named in this version.
What color was the first human?
The results of Cheddar Mans genome analysis align with recent research that has uncovered the convoluted nature of the evolution of human skin tone. The first humans to leave Africa 40,000 years ago are believed to have had dark skin, which would have been advantageous in sunny climates.
What is the largest race in the world?
The worlds largest ethnic group is Han Chinese, with Mandarin being the worlds most spoken language in terms of native speakers. The worlds population is predominantly urban and suburban, and there has been significant migration toward cities and urban centres.
What are the 3 races of humans?
The three great human races: Negroid (left), Caucasoid (center) and Mongoloid (right).

What ethnic group has the highest rate of heart disease?
Blacks have the highest rate of cardiovascular disease in the U.S., with about 47 percent affected. By 2035, that figure is expected to rise to 50 percent.
Can two brothers have same DNA?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. Thats true even for fraternal twins.
Can a human fight a gorilla?
For many humans to beat a mountain gorilla, that would need your strength combined into one person which is even impossible. Mountain gorillas have been killed by humans using weapons but theres no single record of any human ever killing a mountain gorilla using bear hands.
Can a human defeat a chimp?
A new survey has found that 22 per cent of men could defeat a chimp in combat, with a similar number backing themselves to come out on top while wrestling lethal king cobras. Experts say males would stand little chance against chimpanzees, which are four times stronger than humans because of their denser muscle fibre.

Whats the smartest animal on earth?
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
