A pleiotropic gene is a genes which determines the multiple traits.
Pleiotropic gene is a single gene which controls more than one phenotypic trait.
Sickle cell allele is an example of the pleiotropic gene.
Pleiotropy was first discovered by Gregor Mendel. Gregor Mendel is known as the Father of the Genetics.
Types of pleiotropy are:
Gene pleiotropy: focused on the number of traits and biochemical factors impacted by a gene.
Developmental pleiotropy: mainly focuses on mutations and their influence on multiple traits.
Selectional pleiotropy: focuses on the number of separate fitness components affected by a gene mutation.
Antagonistic pleiotropy: mainly focuses on the prevalence of gene mutations that have advantages early in life and disadvantages later in life.
More examples of pleiotropic gene are:
Sickle cell anemia: It is a mutation in beta-globin chain results in changes in blood shape and function.
Phenylketonuria: PKU is caused by a mutation of the gene responsible for the production of an enzyme called phenylalanine hydroxylase.

There are three types of community interaction that can affect an ecosystem. These are the competition, commensalism, and mutualism.
Answer:
high
Explanation:
The resonant color of light that is 40 octaves above an F#4 at standard pitch A4=440 has a frequency of 406.81 THz. This color(drak red) has a wavelength of 736.93 nm. The frequency of an F#4 at standard pitch A4=440 is 369.99 Hz. At a temperature of 72°F (22.22°C), the speed of sound is 345.31 m/sec (1132.91 ft/sec). Under these conditions, an F#4 at standard pitch A4=440 has a wavelength of 93.33 cm (36.74 inches).
You can figure more out by using this equation
wavelength = speedOfLight / frequency
Answer:
The correct description of the relation is reaction velocity always increases with an increase in temperature (option B).
Explanation:
A chemical reaction can be affected by a variety of factors, including the concentration of reactants, pressure and temperature. In the case of temperature, <u>the reaction rate increases depending on the temperature increase</u>.
In a chemical reaction, a temperature -or heat - elevation results in an increase in the speed of motion of each component's particles, while increasing energy and effective shock between them.
<em>
Reaction → heat → increased energy → greater effective shocks of particles</em>.
As a result of this, the relationship between reaction velocity and temperature is that at a higher temperature makes a reaction faster.
