Patrick recently married a cute star girl patti he is considered a purebred for his tall head shape (t) which is dominant over a short head(t) if patti is a short headed starlady what type of heads would their children have.

Al children would have a Tall head shape

Explanation:

Patrick is purebred for the dominant tall head shape so his genotype would be TT. Patti on the other hand is short headed, which is recessive, so the only possible genotype would be tt. If we put that in a Punnet, you can see the result:

TT x tt

    T      T

t  Tt      Tt

t  Tt      Tt

Since all the results are Tt, that means the tall head shape would be expressed because it is dominant and it will mask the recessive trait. So the answer would be:

All children would have a tall head shape.
