Describe the possible effects of mutation on an organism. Describe an example for each effect you mention.
I cant remember. Help please!!
your not helpful but at the same time helpful PsyDAG! Thank you and no thank you
Why can't you just say it clearly man the words they use are confusing and not helpful, you never give a good response
Google "effects of mutation" and read carefully.
No problem! I can explain the possible effects of mutation on an organism and provide examples for each effect. Mutations are changes that occur in an organism's genetic material, which can be caused by various factors such as radiation, chemicals, or errors during DNA replication.
1. Neutral Effect: Some mutations have no noticeable effect on the organism's phenotype (observable characteristics). For example, a single nucleotide substitution (change in one DNA base) in a non-coding region of DNA may not lead to any visible change in the organism, and it would be considered a neutral mutation.
2. Beneficial Effect: Occasionally, mutations can have positive effects on an organism. An example of a beneficial mutation is sickle cell anemia. In areas where malaria is prevalent, individuals with a mutation in the gene responsible for sickle cell anemia have an increased resistance to the disease. This mutation allows them to survive in regions with a high incidence of malaria, providing a selective advantage.
3. Harmful Effect: Mutations can also have harmful effects on an organism, negatively impacting its phenotype and overall fitness. One example is cystic fibrosis, a genetic disorder caused by mutations in the CFTR gene. These mutations lead to the production of a faulty protein that disrupts the functioning of the lungs, digestive system, and other organs, resulting in various health complications.
4. Lethal Effect: Certain mutations can be so severe that they are lethal to the organism. An example is aneuploidy, a condition where the organism has an abnormal number of chromosomes. Down syndrome is an example of aneuploidy caused by the presence of an extra copy of chromosome 21. It can lead to developmental delays, intellectual disabilities, and other health issues.
Remember, these are just a few examples of the effects of mutations on organisms. It is worth noting that the impact of mutations can also vary depending on the specific mutation, the affected genes, and the organism's environment.
