Pedigree analysis is a form of analysis that helps in identifying and determining the risk of getting the genetic disorder in the offsprings by studying and analysing the pattern of inheritance of a particular trait existing in various generation of an individual. The mature messenger RNA is composed only of exons that is later translated into protein. Genome evolution is defined as the process by which genome changes in structure and size with time. Law of dominance: Only one allele of all other alleles is dominant and gets expressed in the case of heterozygous.
