In pea plants, tall [t] is dominant over dwarf [t] plants. a. can two tall pea plants crossed together produce any dwarf pea plants? b. can two dwarf plants crossed together produce any tall plants?

A. In the instance where both of the tall plants were Heterozygous (Tt), there would be a 25% chance for a dwarf offspring, with a 50% of a heterozygous offspring and a remaining 25% chance for the offspring to be Homozygous tall
b. No, because both of the dwarf plants are homozygous recessive, which means that if they were both crossed there would be no chance of a heterozygous offspring nor a homozygous tall offspring.

Competition. interaction among organisms that compete for the same natural resource (food, shelter, water, space) in an ecosystem. predation. an interaction in which one organism kills another for food. predator. prey. symbiosis. mutualisum. commensalisum. parasitisum.
