In a particular species of mammal black hair (B) is dominant to green hair (b) and red eyes (R) are dominant to white eyes (r). If a BbRr individual is mated with a bbrrindividual the expected phenotypic ratio of the offspring is 1 black-red : 1 black-white: 1 green-red : 1 green-white. However, when you mate these individuals you find that the phenotypic ratio of the offspring is 6 black-red :1 black-white : 1 green-red : 6 green-white. What could account for this difference?

Based on their feeding behaviors, three major types of insect herbivores can be distinguished, which evades the constitutive defense;

A) Phloem feeders                                                                    i) caterpillars, grasshoppers, and beetles

B) Cell-content feeders                                                            ii) aphids and whiteflies

C) Chewing insects                                                                    iii) mites and thrips
