Which one of the following is an example of polygenic inheritance?
Which one of the following is an example of polygenic inheritance?
skin colour in humans
flower colour in Mirabilis jalapa
production of male honey bee
pod shape in garden pea
Solution
Inheritance of skin colour in human is controlled by three pairs of genes, $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ which is polygenic inheritance. Codominance is shown by Blood group $\mathrm{AB}$. Chromosomal aberration and point mutation change the genetic sequence of human genome.
