Question
Chapter 29, Problem 14RQ
Summary Introduction
To explain: The way by which an electron micrograph shows that during constriction, the actin and myosin filaments persist constant length while the distance between the Z lines shortens.
Introduction: Muscle constricts in response to the stimulation of a nerve. The striated muscle shows periodic bands, plainly visible under a light microscope. Each striated muscle cell is tube-shaped and multinucleated. It is made up of myofibrils and sarcolemma. Myofibrils are made up of actin and myosin.
Summary Introduction
To explain: The role regulatory proteins troponin and tropomyosin.

There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous.
How many possible genotypes among checkered eagles in the population?
