Zoology - Principles of Inheritance and Variation Question with Solution | TestHub

Consider the four alleles in the population to be A1, A2, A3, A4 and A5. An individual can have only two alleles at a time. So the various genotypes will be A1A1, A1A2, A1A3, A1A4, A1A5, A2A2, A2A3, A2A4, A2A5, A3A3, A3A4, A3A5, A4A4, A4A5, A5A5 (total 15). The general formula for types of genotypes is$\left[\mathrm{n}\left(\mathrm{n}+1\right)\right]/\mathrm{2, }$where n is the number of alleles in the population.
