  1. Null allele

    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, Microsatellite genetics microsatellite s i.e. a repetitive sequence of DNA, in which the repeat is rather short are used as molecular markers amplifying them through Polymerase ... be used and the allele is turned into a null allele.

    Allele frequency or Gene frequency is the proportion of all copies of a gene that is made up of a particular gene variant allele . In other words, it is the number of copies of a particular allele divided ... . It can be expressed for example as a percentage . In population genetics , allele frequencies are used ... species, which contain two sets of chromosomes different alleles of the gene exist one allele exists in a copies then the allele frequency is the fraction or percentage of all the occurrences of that locus that is occupied by a given allele and the frequency of one of the alleles is a n N . 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 . Together, this means that 36 of diploid individuals would be expected to carry an allele that has a frequency of 20 .

  1. Allele-specific oligonucleotide

    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 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 .

  1. Lethal alleles

    Multiple issues orphan February 2009 unreferenced October 2009 Allele s that cause an organism to die only when present in homozygous condition are called lethal alleles . The gene involved is considered 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 heterozygote for the allele will show the lethal phenotype, the homozygote dominant is impossible. If the mutation is caused by a recessive lethal allele, the homozygote for the allele will have the lethal phenotype.

Only those that received the recessive allele from Zygosity both parents present with the recessive phenotype . Those that receive a dominant allele from one parent and a recessive allele from the other parent will have the dominant form of the trait. Purely Mendelian traits are a tiny minority of all traits, since most phenotypic traits exhibit incomplete dominance , codominance , and quantitative trait locus contributions from many genes . The recessive phenotype may theoretically skip any number of generations, lying dormant in Zygosity heterozygous carrier individuals until they have children with someone who also has the recessive allele and both pass it on to their child. Examples These traits include Ability to taste phenylthiocarbamide dominant Ability to smell bitter almond like hydrogen cyanide Albinism recessive Brachydactyly shortness of fingers and toes Wet dominant or dry recessive earwax immunity to poison ivy dominant Thumb Variation Hitchiker s thumb recessive Traits previously believed to be Mendelian Some traits were previously believed to be Mendelian, but their inheritance is probably based on more complex genetic models Citation needed date August 2008 , possibly involving Polygenic more than one gene .

  1. Random match possibility

    Random Match Possibility RMP is a kind of measure in population genetics to measure the possibility of a person random ly picked out of the general population and matching the genotype measured exactly. ref cite web url http www.newscientist.com article mg20727743.300 how dna evidence creates victims of chance.html?full true title How DNA evidence creates victims of chance date 18 August 2010 publisher New Scientist ref A genotype has a number of allele s, and each allele has a allele frequency frequency in a certain race. This frequency is the RMP of that allele. To calculate the RMP of a certain genotype, multiply the frequencies of the alleles in the genotype together. This will give the RMP of the genotype. In forensic science , the evidence from the crime scene is gathered and the genotype of DNA evidence is collected. This is then matched with the suspect. The RMP of the evidence is useful in convincing the jury, because the chances of the genotype of the evidence and that of the suspect matching is very low, and therefore it can hardly be claimed that the suspect is innocent, as the chances of it being so is very low.
