Assertion (A): | Dominance is not an autonomous feature of a gene or the product that it has information for. |
Reason (R): | The frequency of a gene or an allele in a population is ultimately decided by factors such as natural selection. |

I: | Polygenic inheritance takes into account the influence of the environment. |
II: | In a polygenic trait, the phenotype reflects the contribution of each allele, i.e., the effect of each allele is additive. |
III: | The normal distribution curve is bell-shaped in polygenic inheritance. |
IV: | It is also known as quantitative inheritance. |
