Answer: 1) The phenotype of Rr is Pink according to incomplete dominance.
Incomple dominance occurs when none of the alleles is completely dominant over the other, resulting in blending of the phenotype from the parents. When a red (RR) and a white flower (rr) are crossbred, they result in Rr that is a pink phenotype.
2) According to Codominance, the phenotype of Rr is Red and White flower.
Codominance occurs when both the alleles are equally expressed. In this case allele for Red (R) and white (r) phenotype are expressed equally giving Red and White flower.
3) In Codominance, both the alleles are visible in the hybrid and in Incomplete dominance, intermediate (blend of parental) phenotype is visible in the hybrid.
During replication, molecule DNA is copied into new identical molecule DNA. According to the complementary rule, adenine will always bind thymine and vice versa while guanine will always bind cytosine and vice versa. So, if the pairing of bases is perfect during the replication, the offspring will have the same sequence of bases in molecule DNA their parents have.
