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.
Answer
polydactylism
These kitties are born with an abnormal, dominant genetic mutation called polydactylism. While the polydactyl cat's appearance is quite unique, the polydactyl gene is somewhat common. Normally kittens are born with five toes on their front paws and four in the back.
Answer:
Option B, may allow bypass of a blocked coronary artery.
Explanation:
Collateral circulation consists of a network of tiny blood vessels which are nit functional under normal conditions. However, they become functional in case of coronary artery disease.
In coronary artery disease, the coronary arteries narrow down leading to blockage and stopping the flow of blood in the muscles of heart.
In this condition, the collateral circulatory network allows flow of blood around and within the blocked artery thereby protecting heart tissue from injury
Hence, option B is correct
