A test cross.
A Sex Linked sperm Ratio. Not a dihybrid, tets cross, or a Probability.
This question is worded weird, because if someone had a dominant phenotype, as in Brown eyes dominant, than they would be BB or Bb. The exact genotype would need to have a key to what one of their...
The phenotype is determined by the genetic coding within the DNA, and also determined by the genes of an organism.
Different genotypes don't always change your phenotypes because of mutations
