Homozygous for tall is TT
Homozygous for short is tt
All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.

If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.

When two true-breeding plants are crossed, only one result is possible.
