The Law of Independent Assortment proposes alleles for separate traits are passed independently of one another. [38] [35] That is, the biological selection of an allele for one trait has nothing to do with the selection of an allele for any other trait. Mendel found support for this law in his dihybrid cross experiments.
Mendel's second law, the law of independent assortment, states that different traits will be inherited independently by the offspring. Menzerath's law , or Menzerath–Altmann law (named after Paul Menzerath and Gabriel Altmann ), is a linguistic law according to which the increase of a linguistic construct results in a decrease of its ...
The second, the law of independent assortment, states that "alleles of different genes assort independently of one another during gamete formation". Although his work was published, it lay dormant until it was rediscovered in 1900 by Hugo de Vries and Carl Correns but it was not until 1909 that non-mendelian inheritance was even suggested.
This principle of "independent assortment" of genes is fundamental to genetic inheritance. [28] However, the frequency of recombination is actually not the same for all gene combinations. This leads to the notion of " genetic distance ", which is a measure of recombination frequency averaged over a (suitably large) sample of pedigrees.
The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 [5] and 1903, [6] as well as to independent work by Theodor Boveri during roughly the same period. [7] Boveri was studying sea urchins , in which he found that all the chromosomes had to be present for proper embryonic development to take place. [ 8 ]
In cases of intermediate inheritance due to incomplete dominance, the principle of dominance discovered by Mendel does not apply.Nevertheless, the principle of uniformity works, as all offspring in the F 1-generation have the same genotype and same phenotype.
