    How many types of gametes may be produced by genotype D/d: E/e:F/f ?

    A)  27                         

    B)         8

    C)  3                            

    D)         6

    Correct Answer: B

    Solution :

    Kinds of gametes may be calculated by following formula: Number of gametes \[={{(2)}^{n}}\] n is number of alleles Example: D/d : E/e : F/f have trihybrid cross i.e., n = 3 than Kind of gametes \[={{(2)}^{3}}=2\times 2\times 2=8\]
    No. of alleles (n) Trype of cross Formula Kinds of gametes
    (A) (B) (C) (D) (E) Monohybrid cross Dihybrid cross Trihybrid cross Polyhybird cross Polyhybrid cross \[{{(2)}^{1}}=2\times 1\] \[{{(2)}^{2}}=2\times 2\] \[{{(2)}^{3}}=2\times 2\times 2\] \[{{(2)}^{4}}=2\times 2\times 2\times 2\] \[{{(2)}^{5}}=2\times 2\times 2\times 2\times 2\] 2 4 8 16 32
