If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.

What would be the independent variable in the following hypothesis?
Tamiku [17]
The independent variable in the hypothesis of an observed increased in sea turtle sickness once an increase in red tide can be seen would be the increase of red tide. 

The reason for this is that red tide increases or decreases will happen independently of the amount of sea turtle sickness - therefore increasing sea turtle sickness will be dependent on the first variable. (independent one).

The species that is known as a robin in England has a yellow breast, and another species that is known as a robin in the United
Mamont248 [21]
<h3><u>Answer;</u></h3>

C. Different species can share the same common name.

<h3><u>Explanation;</u></h3>
  • <em><u>Different organisms can share the same common name</u></em>, and thus the reason why scientists avoid using common naming while naming organisms.
  • Additionally, s<em><u>cientists avoid using common names because they are not specific to a specific species.</u></em> For instance, Robin is a common word that may be used to describe the many species of robin that are found in different regions of the earth, for example, Robin in England which has yellow breast, and robin in United states and have red breasts.
  • Therefore, <em><u>for the purpose of avoiding ambiguity and confusion in naming organisms scientists use scientific names while identifying various species.</u></em>
