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

Tall head shape

Explanation:

Purebred means that the person has a homozygous genotype. So in the case of Patrick, his genotype would be homozygous dominant, TT. Patti is also homozygous because short head shape is a recessive trait and the only way for it to come out would be if she were homozygous recessive. Now we put that in a Punnet and let's see the results:

TT x tt

    T     T

t   Tt    Tt

t   Tt    Tt

So as you can see all the offsprings have a genotype of Tt. Since tall head shape is dominant it is what will be expressed so all the children would have a tall head shape.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
