Genotype

This study was conducted with the aim of studying the variations by sex and genotype in morphometry of the Oropharyngeal Cavity in Nigerian indigenous chickens. Avian mouth and pharynx do not show any definite line of demarcation, but constitute a common Oropharyngeal Cavity. Generally, anatomical structures found in the dorsal wall of the oropharynx include the palate, choanal slit, and infundibulum, while structures in the ventral wall of the Oropharynx include a concave depression between the rami of the lower beak, laryngeal mound and glottis.

The effects of flood on five genotypes of Cassava (Manihot esculenta), TMEB419, 011371, I98058I, I30574 and 91934 was investigated for a period of twenty (21) days. The plants were subjected to flooding two months after establishment. Results revealed that there are three homogenous groups for chlorophyll A and chlorophyll B. It was observed that the effect of flooding on chlorophyll content of the various genotypes is dependent on time. The longer the duration of flooding the less quantity of chlorophyll in the plant.
