Genetics and Population Biology

I need help on these biology questions:
1. Mutation affect diversity with respect to the effect on alleles?
2. Sexual reproduction affects diversity with respect to the effect on alleles?
3. Population size affects diversity with respect to genetic drift?
4. Migration affects diversity with respect to the effect on alleles?.

1. Mutation affect diversity with respect to the effect on alleles?
Mutation can affect diversity with respect to the effect on alleles because a mutation is actually a permanent, heritable change in the nucleotide sequence of a DNA on the chromosome. (1) Alleles are found on the chromosomes so mutation will change the alleles on the chromosomes, which will lead to genetic diversity. A mutation is actually a change in one or two alleles of a single gene. There are several types of mutation. Point mutation is when one base is deleted on the DNA that can cause a phenotypic change in the gene. They can occur spontaneously and randomly. Mutation creates a change in the DNA that can affect the phenotypic diversity of the genes expressing the traits. For example, a gene can have alleles that encode purple flower. If there is a point mutation that change the sequence of the alleles on the gene, it can change the phenotypic traits of the flower from purple to white. A purple flower will have the genotype PP that encode purple, the mutation can ...

Solution Summary

The mutation affects on diversity with respect to the effect on alleles are given. Sexual reproduction affects diversity with respect to the effect on alleles is examined. Migration affects on diversity with respect to the effects on alleles is given.
