In trees, being tall is dominant to being short. What is the genotype for a short tree?

What is a genotype?
A combination of two or more alleles, found on a gene, that produces a trait
In frogs, having a long tongue is dominant to having a short tongue. What is the phenotype for a frog with the genotype Aa?

What do the letters outside a Punnett square represent?
Alleles from the parent's sex cells
What do the letters inside a Punnett square represent?
Possible genotypes in the offspring (children)
A particular species of bird can be brown or white. The white color is the recessive trait, while the brown color is the dominant trait. When two brown birds mate, is it possible for them to have a white offspring?
Yes, they could both be heterozygous and have a child with a recessive (aa) genotype
