A. A hen and a rooster produce 15 red offspring and 49 black offspring. What are the phenotypes and the genotypes of the parents? (HINT: Think about what ratio 49 black to 15 red is closest to in order to determine the parental genotypes.) If this data is correct, why doesn’t it have to be 15 red offspring and 45 black offspring? b. If one of the red daughter hens were mated with her father (it's okay with chickens), what phenotypes would you expect to find among the progeny (offspring)?

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
