Genetic Mapping Functions

Description

These functions facilitate the conversion between recombination fractions (r) and genetic distances (d) using various mapping models. The functions starting with 'mf_' convert recombination fractions to genetic distances, while those starting with 'imf_' convert genetic distances back into recombination fractions.

Usage

mf_k(d)

mf_h(d)

mf_m(d)

imf_k(r)

imf_h(r)

imf_m(r)

Arguments

d	Numeric or numeric vector, representing genetic distances in centiMorgans (cM) for direct functions (mf_k, mf_h, mf_m).
r	Numeric or numeric vector, representing recombination fractions for inverse functions (imf_k, imf_h, imf_m).

Details

The 'mf_' prefixed functions apply different models to convert recombination fractions into genetic distances:

• mf_k: Kosambi mapping function.

• mf_h: Haldane mapping function.

• mf_m: Morgan mapping function.

The 'imf_' prefixed functions convert genetic distances back into recombination fractions:

• imf_k: Inverse Kosambi mapping function.

• imf_h: Inverse Haldane mapping function.

• imf_m: Inverse Morgan mapping function.
