The beads represent the alleles for a gene that determines the scale color of
a hypothetical species of fish. All of the beads together represent all of the
alleles in the population of fish. Red beads (R) are dominant alleles that code
for the red-scale phenotype. Yellow beads (r) are recessive alleles that code for
the yellow-scale phenotype.
Write the genotype(s) for each phenotype.
