100% Tt
|
|
50% Tt, 50% tt
|
|
75%Tt, 25%tt
|
|
25%TT, 50%Tt, 25%tt
|
Explanation:
Detailed explanation-1: -In a cross between heterozygous tall plants (Tt) and a homozygous dwarf plant (tt), the ratio in the offspring shall be 1 tall : 1 dwarf. This is because the heterozygous plant will make two types of gametes, one type having T allele and the other having t allele. Hence, the correct answer is ‘1 tall : 1 dwarf’
