प्रश्न
Work out a typical Mendelian dihybrid cross and state the law that he derived from it.
Explain dihybrid cross with suitable example
State and explain the "law of independent assortment" in a typical Mendelian dihybrid cross.
उत्तर
Mendel derived ‘the law of independent assortment’ from a dihybrid cross. This law states that the two factors of each character assort or separate independently of the factors of the other characters at the time of gamete formation and get randomly rearranged in the offspring, producing both parental and new combinations of traits.
