Detailed explanation-1: -Genetic factors affect the growth of organisms (plant and animal). The factors that influence the growth of organisms may have more than one cause. Some cause-and-effect relationships in plant and animal systems can only be described using probability. Conduct experiments, collect evidence, and analyze empirical data.
Detailed explanation-2: -Some mutations have a positive effect on the organism in which they occur. They are calledbeneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur.
Detailed explanation-3: -Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation’s probability of being deleterious.
Detailed explanation-4: -Genes involved in human growth consist of major growth genes and minor growth genes. Major growth genes have fundamental effects on human growth, and their mutations cause growth failure (or overgrowth) which are recognizable as single gene disorders.
