Large, diverse societies have put them at odds. Genetics is a term that refers to the study of genes and their roles in inheritance in other words, the way that certain traits or conditions are passed down from one generation to another. This knowledge helps researchers develop new strategies to treat and prevent human disease. Around the world, humans rely on animals for food, fiber, labor and companionship. Mendels experiments demonstrated that when sex cells are formed, the factors for each trait that an individual inherits from its parents are separated into different sex cells. Gregor Mendel is considered. (If heritability of a trait was 100 percent, identical twins, who share the same genetic code, would be exactly the same on that traitbut that doesnt actually happen.).

These are changes in gene function, some of which can be inherited but are not the result of changes in DNA sequence. Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. A geneticist who meets with patients to evaluate, diagnose, and manage genetic disorders is a doctor with special training in genetics, also called a clinical geneticist. Heredity is a biological process. Genetic drift is a change in allele frequency that is random rather than being driven by selection pressures. Welcome to My AP Biology Thoughts podcast, my name is Shriya and I am your host for episode 5 called "Population Genetics: Central Dogma, Allele Frequency Equation and Gene Pools."
