Correct answer: B. Polygenic inheritance
- A. Sex-linked inheritance
- B. Polygenic inheritance
- C. X-linked inheritance
- D. Y-linked inheritance
Explanation
Polygenic inheritance: This option is the correct answer. Human skin color is a good example of polygenic inheritance. Polygenic inheritance occurs when a trait is influenced by multiple genes, each contributing a small effect. Skin color is determined by the combined effects of several genes that control the production and distribution of melanin, the pigment responsible for skin color.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
