A pedigree chart can be defined as a diagram that represents the appearance or occurrence of character of a specific gene or individual and his ancestors for one to next generation.
The pedigree chart is used to identify the inheritance pattern of a specific gene transmit from ancestors to their descendants. It is useful to determine the probability of an organism having a particular genetic disorder.
Thus, the correct answer is option). 'to identify the pattern of inheritance of a particular trait.'
The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait. This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.
