Structures that are specialized for the detection of a stimulus are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Receptors can be classified into three categories based on the stimulus origin, modality, and its location in the body. The encapsulated nerve endings denote nerve fibers that are wrapped in a connective tissue or glial cells, whereas the unencapsulated nerve endings denote dendrites without the wrapping of connective tissues.

Show your calculations. (2 pts) (b) Is this population in Hardy-Weinberg equilibrium? Show your calculations. (3 pts) 12pt v Paragraph BIU UA AV & VT2V f CO V

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
