The number of gametic combinations formed depends upon the heterozygous loci , using the formula 2 n , where n is the number of heterozygous loci . Gametes formed ( A ) BB - I type , number of heterozygous loci = 0 therefore 2 0 = 1 [ B] (B ) T t - 2 types , number of heterozygous = 1 , 2 1 = 2 ,[T ] & [ t] (C) rr - Itype , number of heterozygous loci =0 therefore 2 0 = 1 [r ] ( D ) B b TT - 2types , number of heterozygous = 1 , 2 1 = 2 , [ B t] & [bT] ( E ) BbTt - 4 types , number of heterozygous = 2 , 2 2 =4 , [ BT ] , [Bt ] , [ b T ] , [ b t] (F ) ttrr - Itype , number of heterozygous loci =0 therefore 2 0 = 1 ,[tr] (g )BbTtRr -- 8 types , number of heterozygous loci = 3 , 2 3 = 8 , [ BTR], [ Btr] , [ BTr] , [Bt R] , [bTR] ,[bTr] ,[b t R ], [btr ]Related Questions
