Summary
Elite African athletes do not possess a unique genetic makeup for athletic success. Genetic studies reveal high diversity within East African populations, not a specific advantage for elite performance.
Area of Science:
- Sports Science
- Human Genetics
- Exercise Physiology
Background:
- Elite athletic performance is influenced by both environmental factors (training, diet) and potential genetic components.
- East African dominance in distance running and West African success in sprinting have fueled speculation about inherent genetic advantages.
- Despite anecdotal evidence, scientific investigation into the genetic basis of athletic prowess in African athletes is limited.
Purpose of the Study:
- To investigate the genetic basis of elite athletic performance in African athletes.
- To determine if specific genetic variations predispose East Africans to distance running or West Africans to sprinting.
- To analyze the genetic diversity within elite African athlete populations.
Main Methods:
- Review of existing genetic studies on elite African athletes.
- Analysis of genetic variation data in East and West African populations.
- Comparison of genetic profiles of elite athletes with general populations.
Main Results:
- Current genetic evidence does not support the hypothesis of a unique genetic advantage in elite African athletes.
- Studies highlight significant genetic diversity within East African populations, including elite athletes.
- No specific genetic makeup has been identified that explains the success of African athletes in endurance or sprint events.
Conclusions:
- The success of elite African athletes is not attributable to a singular, inherent genetic advantage.
- Genetic diversity within African populations is substantial and contributes to the varied athletic achievements observed.
- Further research is needed to fully understand the complex interplay of genetics and environment in athletic performance.

01:25Genetic Variation
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
