A Mutation occurring in the population will change the allelic ratio.
<h3>What is evolution?</h3>
Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.
One of the factors of evolution is mutation.
According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.
Therefore, if a mutation occurs in the population, the allelic ratio will change.

Answer;
-The above statement is true
-It is a precaution during dissecting.
Explanation;
Among the precautions while dissecting include;
-When cutting into or dissecting the specimen, it is important to always cut away from yourself and others. To avoid cutting anyone, especially with formaldehyde being used. .
-You should also should not hold the animals while cutting because you could again, cut yourself. Another precaution that should be obvious is Do not eat any part of the specimen.
Answer:
The correct answer is internal and external signals regulate the progression of the cell cycle at various critical check points.
Explanation:
The cyclic event that helps to prepare the cell for division is termed as cell cycle.Cell cycle are regulated by various internal and external factors which regulates the passage of cell through various critical check point.
For example Maturation promoting factor helps in the progression of frog egg oocytes cells from G2 to M phase.
G1 cyclin CDK helps in the passage of cell from G1 to S phase.
Answer:
The formula is 2n - 2
Since n is 30
= 2(30) - 2
= 60 - 2
= 58
A mutant nullisomic version of this organism would have 58 chromosomes.
A diploid cell missing both copies of the same chromosome exhibits a nullisomic condition or a cell or individual with one chromosomal type missing. Humans having this condition will not live.
