If tall is dominant to short in plants and yellow is dominant to green, what are the possible genotypes and phenotypes of  the offspring  of a heterozygous tall, yellow plant and a short green plant?

In such a crossing, where a heterozygous tall yellow plant is defined on a Punnett square as TtYy, and a short green plant is defined as ttyy, 50% of your offspring will remain heterozygous tall yellow plants (TtYy) and 50% of your offspring will be homozygous short green plants (ttyy)
