Method synopsis

Monte Carlo simulation comparing observed reproductive pair relatedness to expected relatedness under random mating to test for inbreeding avoidance.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — No evidence of inbreeding avoidance despite survival costs in a polygynous rodent (2012), Molecular Ecology. Implementations in other papers (listed below) may differ.

1. Randomization procedure for inbreeding avoidance
   Performed randomizations in MATLAB v.7.12 using the built-in 'randsample' function. Performed 10,000 iterations for each year, with the number of pairs selected at each iteration determined by the number of offspring produced in each area. Randomly drew pairs from among all possible combinations of females and males in each geographic group and calculated the mean relatedness of all chosen reproductive pairs
   Quantities: 10,000 iterations per year, separate analyses for 'up valley' and 'down valley' groupsDuration: Computational analysis for years 2003-2008Conditions: Computational analysis conditions
   Equipment: MATLAB v.7.12

Typical Equipment

• MATLAB v.7.12
