⚪️ℚ𝕌𝕀ℂ𝕂 𝕋𝕀ℙ𝕊 ✅ Quick tip to determine the number of gametes ✅ Formula = 2^n, where n = number of heterozygous allele pairs. ✅ Example: Determine the number of gametes in genotype AaBBCcDD. ✅Solution: In AaBBCcDD heterozygous is Aa and Cc = 2 ✅ Formula: 2^n; 2^2 = 4 ✅ Therefore, four types of gametes will be formed. These are, ✅ ABcD, ABCD, aBcD, aBCD
