Yesterday I asked my Biology Teacher about Hets and etc.

She make a little chart which explained what the offspring would look like.

The chart at the top shows 2 Leops, one Normal(A), one Het(a), since the normal has the Stronger genes(becauses its not a het) it will have the Capital letter and when breeded with (a) The offspring will look like (A).

The new look would make a (Aa). It would look like (A) but also have some genes with (a). and just a note as you know Aa is a Het now.

Now what would I get if I breed my new (Aa) with a (a)?

Look at the picture.

those would be your aa's or the recessive morph the het was het for.

Both of those squares are screwy, so either your biology teacher didn't explain it right, or you just didn't quite grasp it.

Normal is a phenotype, the genotype (genetic makeup) can be either AA (two dominant alleles) or Aa (dominant and recessive). A genotype of aa would cause the animal's phenotype to be the recessive trait. For each trait, an animal will have 2 alleles, not 3 and not 1. So your bottom chart doesn't make any sense. Neither do one of the results of the top chart.
