TT,Tt,Tt,tt

Answer 2

Total types of gametes produced in monohybrid back cross of capital Tt and TT plants is two(option - 2)

• The types of gametes produced are given by the number of heterozygous individuals.
• Types of gametes = 2ⁿ, n = number of heterozygous individuals.
• Back cross is when an offspring is crossed with one of its parents.
• In this case TT × Tt, only one heterozygous individual is present i.e. Tt, hence 2¹ = 2.
• Therefore, two types of gametes will be produced.
• Heterozygous individuals are those who consist of 2 different types of alleles for the same trait.
• TT can produce gametes = T only.
• Tt can produce gametes = T and t.
• Therefore, only 2 types of gametes are produced T and t.
