A neutral mutation arises in a diploid population of 10,000 individuals. Use this information to answer the following questions. a) What is the probability that the neutral allele goes to fixation? b) Assuming that the neutral mutation eventually goes to fixation, what is the expected time to fixation (in generations)?
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

Mutation refers to a change in the nucleotide sequence of the DNA contained in the genome of an organism. DNA is composed of repeating units of nitrogenous bases supported by a sugar-phosphate backbone bound to each base. A specific DNA sequence makes up a gene that codes for a protein. Any change in this gene sequence may lead to a different protein than the normal known as a mutated protein.
A neutral mutation is a type of genetic mutation that occurs in an organism's DNA sequence without affecting the function or fitness of the organism. It does not result in any observable changes in the organism's phenotype, survival, and reproductive success. These mutations can involve substitutions of one nucleotide for another without altering the amino acid sequence of the protein encoded by the gene.
