Polygenic Inheritance
Polygenic inheritance is a type of inheritance in which a trait is controlled by three or more genes. It is a complex form of inheritance that results in a range of phenotypes. Here are the correct statements regarding polygenic inheritance:
1. Controlled by three or more genes
Polygenic inheritance is controlled by three or more genes. These genes are located on different chromosomes and each gene contributes a small amount to the final phenotype.
2. Not influenced by environment
Polygenic inheritance is not influenced by the environment. The phenotype is solely determined by the genotype of the individual.
3. Phenotype reflects the contribution of all alleles
In polygenic inheritance, the phenotype reflects the contribution of all alleles, both dominant and recessive. The final phenotype is a result of the combined effect of all the genes involved.
Therefore, the correct answer is option 'D' - only statement 2 is correct.
