Vedclass · Answer

(B) Gibberellin is a plant growth hormone that can induce stem elongation,making a genetically dwarf plant appear tall phenotypically. However,the genotype of the dwarf plant remains homozygous recessive $(tt)$.When this phenotypically tall (but genotypically $tt$) plant is crossed with a pure tall plant (genotype $TT$),the cross is $tt 	imes TT$.The gametes produced by the $tt$ plant are all $t$,and the gametes produced by the $TT$ plant are all $T$.The resulting $F_1$ generation will have the genotype $Tt$.Since $T$ (tall) is dominant over $t$ (dwarf),all offspring in the $F_1$ generation will be tall.

If a dwarf plant is treated with gibberellin,it becomes tall. If this plant is now crossed with a pure tall plant,what will be the progeny of the $F_1$ generation?
