 Phenotype

You picked these children. Are they ours?

No, these are not our children.
The tall one could have gotten a blue gene from each parent, but only one parent has genes for TALL.

This child, who has two genes for TALL, could not be ours.

The short child could also have two blue genes, one from each parent. However, only one parent has genes for not-tall, and this child has two NOT TALL genes.

This child could not belong to these parents.

Please hurry back and find our children for us!!!
