What is the chance of pollen grains of genotype T pollinating eggs of genotype t?

Options

  1. A25%
  2. B50%
  3. C75%
  4. D100%

Correct answer

B. 50%

Step-by-step solution

When fertilisation takes place, the pollen grains of genotype T have a 50 per cent chance to pollinate eggs of the genotype T, as well as of genotype t . Also pollen grains of genotype t have a 50 per cent chance of pollinating eggs of genotype T, as well as of genotype t. As a result of random fertilisation, the resultant zygotes can be of the genotypes TT, Tt or tt.
