I need my answers checked please:
Q: Natural selection causes changes in
1. Individuals
2. Populations <-
3. Genotypes
4. Phenotypes
Q: Which statement is accurate about natural selection?
1. Natural selection does not impact reproduction rates.
2. Natural selection cannot inactivate genes.
3. Natural selection does not change the alleles an organism has. <-
4. Natural selection cannot occur through mutations.
Q: Which mutation scenario will always lead to natural selection?
1. a mutation causes a specific advantage within the population <-
2. a mutation causes an inactivated gene to be reactivated
3. a mutation causes a gene to become inactivated
4. a mutation causes a specific variation within the population
Q: Consider the following scenario:
There are variations in the fur color of mice. Some mice have white fur. Some have dark fur. Foxes more easily catch mice with white fur.
What will likely be a consequence of this scenario?
1. Mice with white fur will be more likely to survive and reproduce.
2. Brown fur will become predominant. <-
3. White fur will become predominant.
4. Mice with brown fur will be less likely to pass on their genetic information.
Q: What evolves during natural selection?
1. the proportion of different traits in a population
2. Entire species
3. Inactivated genes
4. the phenotypes of individual organisms <-
Thanks in advance!
