Vedclass · Answer

(A) The phenotype of an organism is determined by its genotype and the environment. Growth hormones (like gibberellins) can induce temporary phenotypic changes in a plant,making a genetically dwarf plant appear tall. However,these changes are purely physiological and do not alter the genetic makeup (genotype) of the plant. The genotype of the dwarf plant remains homozygous recessive $(tt)$. When this treated dwarf plant $(tt)$ is crossed with another dwarf plant $(tt)$,all offspring in the $F_1$ generation will have the genotype $tt$. Therefore,all offspring will be phenotypically dwarf.

If a dwarf plant is treated with a growth hormone and then crossed with a dwarf plant,what will be the phenotype of the $F_1$ generation?

Mendel was lucky, because

Mendel crossed tall and dwarf plants. In the $F_{2}$-generation,the observed ratio was $3: 1$ (tall: short). From this result,he deduced:
