The type of inheritance in which many traits of a character are spead across a gradient and the effect of each allele is additive, is

Which of the following statements is / are correct for a polygenic inheritance ? 1. They show uniformity. 2. Controlled by three or more genes. 3. It is not influenced by the environment . In polygenic inheritance, phenotype reflects the contribution of recessive allele only .

Assertion (A): Polygenic inheritance gives rise to varied skin tones in F_(2) generation. Reason ( R): Phenotype reflects the contribution of each allele, is influenced by the environment in case of polygenic inheritance.

Assertion : A gamete contains a single allele for each trait. Reason : During gametogenesis, the two alleles of each trait segregate, on passing into each gamete at random.
