Suppose a species of tulip has three alleles for the gene that codes for flower color. The <img src="https://tex.z-dn.net/?f=C%5
givi [52]

Answer:

1. 2 red: 2 purple

2. 2 red: 1 purple: 1 white

Explanation:

For this question, you need to create two separate punnett squares. The first punnett square would have C^R over one square with C^P in the square next to it, and on the other side would C^P next to one square and C^W next to the square below it. It doesn't matter what side you put the alleles on, just make sure the same alleles of the same flower are on the same side. Then, in order to find the phenotype, or in this case the color of the flowers' offspring, follow the dominance rules the question gave you. Remember, alleles don't have to be homozygous to determine what color they will be. Just make sure that the dominant allele is the allele used to determine the color. The same rules will apply for the second punnett square, and then you should get your answer. Hope this helps! :)
