Answer 3

The most accurate answer is test cross. A test cross is when you don't know the genotype of one parent - so you cross it with an individual who's genotype you know is homozygous recessive.

If all the offspring have the dominant phenotype, you know they got the dominant alleles from the unknown parent, so that parent was homozygous dominant.

If half the offspring have the dominant phenotype, you know the unknown parent you were testing was heterozygous.

And if all the offspring have the recessive phenotype, you know that the unknown parent must be homozygous recessive.
