SYLLABUS I External Marks 40 Internal Assessment 10 Time allotted 3 Hours Note Nine questions are to be set in all and the candidate are required to attempt five questions including c ompuls. Recent studies in genetics suggest that anatomically modem humans emerged at a very late date perhaps 50 kys Bertrapetit 2000 Thompson 2000 This dating is consistent with the onset of an unprecedented degree of cultural innovations in both quality a By: Keith King. Objectives. State the history of genetics;. Describe major century events;. Define terms used in genetics . History of Genetics. People have known about inheritance for a long time.. --children resemble their parents. 1. Phylum Annelida. Class Polychaeta. Class Clitellata. Phylum Annelida. 2. Annelid Characteristics. Defining Characteristics. One or more pairs of chitinous setae. The phylum includes polychaetes, earthworms, leeches, and vestimentiferans. Today we will study the annelids, the segmented worms, and the arthropods, a huge group that contains insects, spiders, and crustaceans. Three tissue layers are present in both of these groups. Also -. Arthropoda. -. (insects, crustaceans, spiders, mites) . Arthropoda. - insects, crustaceans, spiders, mites, . Arthropoda - abundance . Arthropoda. – . Where did they come from?. Peripatus. What about the Onychophora (“velvet worms” )? . -. Arthropoda. –. Insects and Crustaceans. Arthropoda - Crustacea - lobsters, crabs, barnacles. Arthropoda - Crustacea - lobsters, crabs, barnacles.
