Unreferenced date December 2009 A null allele is a mutant allele copy of a gene that completely lacks that gene s normal function. This can be the result of the complete absence of the gene product protein, RNA at the molecular level, or the expression of a non functional gene product. At the phenotype phenotypic level, a null allele is indistinguishable from a deletion of the entire locus genetics locus . A mutant allele that produces no protein is called a protein null shown by Western blot Western analysis , and one that produces no RNA is called an RNA null shown by Northern blot Northern analysis or by DNA sequencing of a deletion allele . A genetic null or Muller s morphs amorph ic allele has the same phenotype when homozygous as when heterozygous with a deficiency that disrupts the locus in question. A genetic null allele can be a protein and RNA null, but can also express normal levels of a gene product that is non functional due to mutation. Another definition of null allele concerning molecular markers, refers to such a marker in the case it can no longer be detected because of a mutation.

For example, if the frequency of an allele is 20 in a given population, then among population members, one in five chromosomes will carry that allele. Four out of five will be occupied by other variant s of the gene. Note that for diploid genes the fraction of individuals that carry this allele may be nearly two in five 36 . The reason for this is that if the allele distributes random ly, then the binomial theorem will apply 32 of the population will be heterozygous for the allele i.e. carry one copy of that allele and one copy of another in each somatic cell and 4 will be homozygous carrying two copies of the allele .

An allele specific oligonucleotide ASO is a short piece of synthetic DNA complementary to the sequence of a variable target DNA. It acts as a Hybridization probe probe for the presence of the target in a Southern blot assay or, more commonly, in the simpler Dot blot assay. It is a common tool used in genetic testing , forensics , and Molecular Biology research. An ASO is typically an oligonucleotide of 15&ndash 21 nucleotide nucleotide bases in length. It is designed and used in a way that makes it specific for only one version, or allele , of the DNA being tested. The length of the ASO, which strand it is chosen from, and the conditions by which it is Nucleic acid hybridization bound to and washed from the target DNA all play a role in its specificity. These probes can usually be designed to detect a difference of as little as 1 base in the target s genetic sequence, a basic ability in the assay of single nucleotide polymorphism s SNPs , important in genotype genotype analysis and the Human Genome Project .

Genetic hitchhiking is the process by which an evolution arily neutral or deleterious allele or mutation may spread through the gene pool by virtue of being linked to a gene that is positively selected. ref Cite journal doi 10.1098 rstb.2000.0716 pmid 11127900 volume 355 issue 1403 pages 1553 1562 last Barton first N H title Genetic hitchhiking journal Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences accessdate 2009 09 23 date 2000 11 29 pmc 1692896 ref More generally, genetic hitchhiking can refer to the process by which a gene s frequency changes due to selection operating upon linked genes. Proximity on a chromosome may allow genes to be dragged through the selection process due to an advantageous gene nearby. The most often cited example of this is one of a hypothetical mutator which increases the general mutation mutation rate in the area around it. M A On this chromosome the gene M is a mutator allele, increasing the rate of mutation in the surrounding area. A is an allele which is at fixation in the population that is, all individuals possess this allele in the homozygous state. Due to the increased mutation rate, the A allele may be mutated into a new, advantageous allele, A . M A The individual in which this chromosome lies will now have a selective advantage over other individuals of this species, so the allele A will spread through the population by the normal processes of evolution natural selection . M, due to its proximity to A , will be dragged through into the general population. This process only works when M is very close to the allele it has mutated. A greater distance would increase the chance of recombination separating M from A , leaving M alone with any deleterious mutations it may have caused. For this reason ... allele to appear, but genetic hitchhiking can also happen by chance alone. Whether a neutral allele becomes fixed is a matter of chance. The traditional view of this stochastic process is that it is dominated ... more details
Multiple issues orphan February 2009 cleanup May 2007 unreferenced October 2009 Allele s that cause an organism to die are called lethal alleles , where the gene involved is an essential gene. When Mendel s Laws were rediscovered, geneticist s believed that mutation s would only alter the appearance of a living organism. However, it was discovered that a mutant allele could cause death. When an essential gene is mutated, it can result in a lethal phenotype . If the mutation is caused by a dominant lethal allele, the homozygote and heterozygote for the allele will show the lethal phenotype. If the mutation is caused by a recessive lethal allele, the homozygote for the allele will have the lethal phenotype. Most lethal genes are recessive. Examples Examples of diseases caused by recessive lethal alleles are cystic fibrosis , Tay Sachs disease , sickle cell anemia , and brachydactyly . Huntington s disease is caused by a dominant lethal allele and even though it is not described as lethal, it is invariably lethal in that the victim experiences gradual neural degeneration and mental deterioration for some years before death occurs. One coat color of ranch fox es is caused by recessive lethal gene. This gene causes a death if both recessive alleles are possessed by the same individual. Recessive lethal alleles don t cause death in the heterozygous form because a certain threshold of protein output is maintained. In the homozygous form, the protein output doesn t meet the threshold, causing death.
