kosambi's Function

D.D.Kosambi (1907-1966)was an Indian mathematician whose contribution in genetics is remembered after name along with a mathematical expression as Haldane function. As per his equation genetic map distnance(w) is related to recombination fraction (θ) in the following way... w = 1/4 ln[(1+2θ)/(1-2θ)]

or in other sense … θ = 0.5[ exp4w- 1/(exp4w+1)] Kosambi’s mapping function adjusts the map distance based on interference which changes the proportion of double crossovers.(To know more about is you can happily explore the given website ''https://www.academia.edu/665254/Kosambi_and_the_genetic_mapping_function
