Abstract:
Many fishes living in reef environments display remarkable flexibility in sexuality with social interactions determining their sex either during juvenile development or in adulthood. The evolutionary advantages of such flexibility are relatively well established. By contrast, the mechanisms by which social cues guide development of the sexual phenotype are less well understood. This paper reviews our understanding of these processes for some well-studied reef fish groups at the gonadal and neuroendocrine levels as well as proposing promising directions for future study.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
