A Mathematical Model for Solving Four Point Test Cross in Genetics
... Recombination frequency is a measure of genetic linkage [7], [8] and is used in the creation of a genetic linkage map. Recombination frequency (denoted by θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis. A centimorgan (cM) is a unit that ...

Genes and MS
... There is no reliable test for genes which play a part in MS. There are several reasons for this: - There is no single 'MS gene'. Research suggests that between 50 and 100 different genes might play a part in the development of MS. So far, only a few of these genes have been identified. - The genes t ...
