It is the process of formation of a new species from existing ones due to several evolutionary forces like genetic drift, isolation of populations, natural selection, etc. It is called the dominant gene and it expresses in any possible combination. These differences lead to different/varied physical characters or biochemical pathways. 8. The evolutionary relationship among different biological species is called phylogeny. After a successful expedition on HMS Beagle, Charles Darwin wrote a book on what he observed at the Galapagos Islands. The rules of heredity determine the process by which traits and characteristics are reliably inherited. The traits that are inherited from the parents are called inherited characters. Natural selection can play an important role in deciding the traits that survive in a population. Heredity and evolution Worksheet-1 .
