Answer: The phenotype ratio is 3:1

Explanation: If T represents tall trait and is dominant over t which is the recessive trait, there are 1 homozygous tall (TT), 2 heterozygous tall (Tt) and 1 homozygous short (tt) offsprings. All homozygous tall and heterozygous tall offsprings will appear outwardly as tall while the homozygous short offspring will appear outwardly as short. Therefore the phenotype ratio is 3:1

For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period.
