Direction: In the following questions a statement of assertion (A) is...
Quantitative inheritance is a type of inheritance controlled by one or more genes in which the dominant alleles have cumulative effect with each dominant allele expressing a part or unit of the trait, the full trait being shown only when all the dominant alleles are present. The genes involved in quantitative inheritance are called polygenes. A polygene is defined as a gene where a dominant allele controls only a unit or partial quantitative expression of a trait.

Direction: In the following questions a statement of assertion (A) is...
Assertion : Quantitative inheritance is called polygenic inheritance.
Reason : Several genes control the expression of a trait.
The correct answer is option 'A': Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Quantitative inheritance, also known as polygenic inheritance, refers to the inheritance of traits that are controlled by multiple genes. In such cases, the phenotype is determined by the cumulative effect of several genes, each contributing a small effect to the overall phenotype.
Several genes control the expression of a trait is the reason given for the assertion. This reason is correct because polygenic traits are controlled by multiple genes, each contributing to the expression of the trait. These genes may interact with each other and with the environment to determine the final phenotype.
For example, height in humans is a polygenic trait. Multiple genes contribute to determining an individual's height, and each gene may have different alleles that can influence the height. The combined effect of these genes determines the overall height of an individual.
Polygenic inheritance can often be observed as a continuous variation of a trait in a population, rather than distinct categories or phenotypes. This is because the effects of multiple genes are combined, resulting in a range of phenotypic variation.
In conclusion, the assertion that quantitative inheritance is called polygenic inheritance is true, and the reason that several genes control the expression of a trait is the correct explanation for this assertion.
