Capt. Jack Sparrow’s “weird” way in running is a homozygous trait ( r ) that only certain pirates possess. If Jack Sparrow decides to marry another female pirate who is heterozygous for normal running, what would be the genotypes of their potential offspring?

How could you find the genotype of an individual that is unknown? Test Cross
Mimicking noises is a dominant trait for the Lyrebird. The recessive condition makes it so the bird is not able to mimic any noises.
A mimicking male bird and a non-mimicking female bird are crossed, however you do not know the exact genotype of the mimicking male bird. Show ALL the Punnettsquares which could represent this cross.
