Retriever and Pointer: Software to Evaluate Inbreeding and Genetic Management in Captive Populations

Area of Science:

• Animal Genetics
• Population Genetics
• Conservation Biology

Background:

• Effective genetic management is crucial for the long-term viability of small captive populations.
• Inbreeding and loss of genetic diversity pose significant threats to these populations.

Purpose of the Study:

• To introduce the Retriever and Pointer software for genetic management of captive populations.
• To provide tools for analyzing population structure and simulating genetic management strategies.

Main Methods:

• Retriever program analyzes pedigree data to assess population structure, inbreeding rates, and effective population sizes.
• Pointer program uses stochastic simulation to evaluate populations, predict inbreeding and kinship levels, and assess allelic diversity.
• Both programs handle populations with sub-populations and inter-population exchange rates.

Main Results:

• The software quantifies inbreeding rates, kinship, and effective population sizes.
• Simulation capabilities allow users to test various management options like sire restrictions and inbreeding limits.
• The software is applicable to diverse captive populations, including livestock, zoo animals, and dogs.

Conclusions:

• Retriever and Pointer software offer valuable tools for optimizing genetic management in captive populations.
• The software facilitates informed decision-making to mitigate inbreeding and preserve genetic diversity.
• Pointer software is also suitable for educational purposes, demonstrating population genetics principles.
