Natural Selection and Mutant Genes in Population

Natural selection is a process in which organisms that are better adapted to their environment tend to survive and produce more offspring. Mutant genes are new genetic variations that arise in a population due to genetic mutations. In the population of a species, chances of the spreading of a mutant gene increases when natural selection occurs.

Explanation:

- Recessive and Dominant Gene:
Recessive and dominant genes are terms used to describe the inheritance patterns of specific traits. A recessive gene is one that is only expressed when an individual has two copies of that gene. A dominant gene is one that is always expressed when an individual has at least one copy of the gene.

- Mutant Gene:
A mutant gene is a new genetic variation that arises in a population due to genetic mutations. Mutations are changes in the DNA sequence that can result in new traits or variations in existing traits.

- Natural Selection:
Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring. This results in the spread of favorable traits throughout the population.

- Chances of Spreading of Mutant Gene:
The chances of the spreading of a mutant gene increases when natural selection occurs. This is because if the mutant gene provides a survival advantage to the organism, then those organisms with the gene will be more likely to survive and reproduce. Over time, this will result in the spread of the mutant gene throughout the population.

- Dominant and Recessive Genes and Mutant Gene:
Dominant and recessive genes do not necessarily affect the chances of the spreading of a mutant gene. Whether a gene is dominant or recessive only determines how the trait is expressed in an individual. The effects of the mutant gene on the survival and reproduction of the organism are what determines whether it will spread throughout the population.

Conclusion:

In conclusion, the chances of the spreading of a mutant gene in the population of a species increases when natural selection occurs. The inheritance pattern of the gene, whether it is dominant or recessive, does not necessarily affect its spread. It is the effects of the gene on the survival and reproduction of the organism that determine its spread throughout the population.
