A plant is heterozygous for tallness (Tt). The possibility of‘t’ gamete fertilizing eitherTor ‘t’ is(A) \(\frac{1}{8}\)(B) \(\frac{1}{2}\)(C) \(\frac{1}{4}\)(D) \(\frac{1}{6}\) |

Answer» (B) \(\frac{1}{2}\) Plant heterozygous for tallness has two alleles, one governing tallness and other governing dwarfness. This plant will produce two types of gametes during gamete formation because of segregation. The gametes produced are T and t. Hence, the possibility of ‘t’ gamete fertilizing either ‘T’ or ‘t’ is \(\frac{1}{2},\) i.e. 50 %. |
