Need biology help please!?

The answer to the question is (c). We can eliminate answers (d) and (b) because the two plants would have the same phenotype (in this case, flower color) because they both have the same genotype (allele type). To get answer (c), use a Punnett square chart. This is simply a 2 by 2 grid. Try both (a) and (c). When you try (c), you will find that there are two different genotypes, and they each occur an equal number of times (2). Thus, one half (2/4 because you get two of the same genotype over 4 possible genotypes) of the flowers' offspring are of each color.
