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) | Type of cross | Formula | Kinds of gametes |
| 1 2 3 4 5 | Monohybird cross Dihybrid Cross Trihybrid Cross Polyhybrid 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 |
