expectedHomozygosity

expectedHeterozygosity

Computes the expected homozygosity and heterozygosity for a marker from its
allele frequencies. The homozygosity is \(\sum_i p_i^2\) and the
heterozygosity is one minus this.

A comprehensive collection of tools for creating,
manipulating and visualising pedigrees and genetic marker data.
Pedigrees can be read from text files or created on the fly with
built-in functions. A range of utilities enable modifications like
adding or removing individuals, breaking loops, and merging pedigrees.
An online tool for creating pedigrees interactively, based on
'pedtools', is available at <https://magnusdv.shinyapps.io/quickped>.
'pedtools' is the hub of the 'pedsuite', a collection of packages for
pedigree analysis. A detailed presentation of the 'pedsuite' is given
in the book 'Pedigree Analysis in R' (Vigeland, 2021,
ISBN:9780128244302).
