Question

Identify the wrong statement :-

• A. Probability of homozygous dwarf progeny in a cross TT $\times$ Tt is zero
• B. Probability of homozygous tall progeny in a cross TT $\times$ TT is one
• C. Probability of heterozygous tall progeny in a cross TT $\times$ tt is 0.5
• D. Probability of homozygous dwarf progeny in a cross TT $\times$ TT is zero.

Answer 1

The correct option is C Probability of heterozygous tall progeny in a cross TT $\times$ tt is 0.5

A.Probability of homozygous dwarf progeny in a cross TT x Tt is zero – True because in this cross all progeny formed are tall,either homozygous or heterozygous.

B.Probability of homozygous tall progeny in a cross TT x TT is one – True, because all progeny formed in the cross are tall.

C.Probability of heterozygous tall progeny in a cross TT x tt is 0.5 – False, because, all the progeny are formed are heterozygous and the probability is 1.

D.Probability of homozygous dwarf progeny in a cross TT x TT is zero – True, because in this cross not dwarf progeny is involved.

So, the correct option is ‘Probability of heterozygous tall progeny in a cross TT x tt is 0.5’.
