Answer:
Pleiotropy.
Explanation:
Pleiotropy may be defined as when the single gene shows the multiple phenotypic traits. The gene is known as the pleiotropic gene and its mutation may affect the several phenotype expression.
The frizzle gene control the multiple phenotype effects like defective feathers, high blood flow, low egg lay rates and high metabolic rates. This is a case of pleiotropy because here a single gene is responsible for the multiple phenotypes.
Thus, the answer is pleiotropy.
The statement "The correct way to calculate population size is by dividing the total population by the land area." is true. The correct option is A.
<h3>What is the population?</h3>
The entire number of species in a given area makes up the population. Surveys of various places are conducted to determine the population. By dividing the total population by the fraction of each individual, the population size can be determined.
There are various techniques for population counting. Cohort analysis, aerial counts, etc., are some of these techniques.
Thus, the statement is true. The correct option is A.

Answer:
c, disruptive selection
Explanation:
Disruptive selection is a term used to describe population genetic changes that simultaneously favor individuals at both ends of the distribution. When disruptive selection operates, individuals at the extremes contribute more offspring than those with intermediate characteristics, producing two peaks in the distribution on a graph.
In the excerpt shown in the question, long-gill-striped and gill-striped fish were favored by the selection process than intermediate-length striped fish. For this reason we can conclude that a disruptive selection was taking place.
Enzymes contain a globular protein part called apoenzyme and a non-protein part named cofactor or prosthetic group or metal-ion-activator.
