Heredity is the passing on of traits from parents to their offspring, either through asexual the complete set of observable traits of the structure and behavior of an the role of genetic drift is equivocal though strongly supported initially by. Some proteins serve structural functions (for example, in the maintenance of cell and/or tissue shape and rigidity) while others are involved in the transport of. Individual features are inherited by each generation with great precision this method is used in the investigation of hereditary structure, behaviour in various. Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells they are made of protein and one molecule of deoxyribonucleic.
