Vedclass · Answer

(C) recessive trait is expressed only when both alleles are recessive (homozygous recessive,$tt$).In option $A$ $(TT 	imes tt)$,all progeny will be $Tt$ (dominant phenotype).In option $B$ $(Tt 	imes TT)$,progeny will be $TT$ or $Tt$ (all dominant phenotype).In option $C$ $(tt 	imes tt)$,all progeny will be $tt$,which expresses the recessive trait.In option $D$ $(TT 	imes TT)$,all progeny will be $TT$ (dominant phenotype).Therefore,only the cross $tt 	imes tt$ produces recessive progeny.
