Which of the following is the best explanation for a child who is phenotypically short and born of two tall parents

A child who is phenotypically short and born of two tall parents can be explained by the presence of genes for shortness in both parents. Our physical characteristics, such as height, are determined by a combination of genes inherited from both parents. Just because a parent is tall doesn't mean they don't carry genes for shortness. When two carriers of the gene for shortness have a child, there is a chance that the child will inherit two copies of the gene and express the short phenotype. This is an example of how dominant and recessive genes can interact and result in a phenotype that is different from the parents.
