10 Interesting Fact About The science of genetics and heredity

Transcript:

Languages:

• Genetics is the study of inheritance from parents to children.
• Humans have about 20,000-25,000 genes in their bodies.
• There are more than 3 billion pairs of DNA bases in human genomes.
• Genes can be inherited from our great-grandfather, even to the fourth generation.
• Genes in humans have a very high possibility of variations, so that everyone has a unique genetic difference.
• Genetics has helped in the development of genetic engineering technology, such as cloning and genetic modification of plants.
• Inheritance in humans can be determined through DNA analysis, such as hereditary tests and paternity tests.
• Some genetic diseases can be inherited from parents to children, such as thalassemia and hemophilia.
• The discovery of DNA double helical structure by Watson and Crick in 1953 was a major achievement in the genetic field.
• Genetic studies in animals and plants also provide a deeper understanding of evolution and biodiversity on earth.
