Researchers can now easily check genetic data for errors using Checkfam, a web-based program. This tool helps identify and correct Mendelian inheritance contradictions for accurate linkage analysis.

Area of Science:

  • Genetics
  • Bioinformatics

Background:

  • Accurate linkage analysis relies on error-free genotypic and pedigree data.
  • Contradictions in Mendelian inheritance patterns often stem from genotyping or pedigree errors.

Purpose of the Study:

  • To implement an accessible, web-based error-checking algorithm for genetic data.
  • To assist researchers in identifying and resolving Mendelian inheritance contradictions.

Main Methods:

  • Developed Checkfam, a World Wide Web-based program utilizing two error-checking algorithms.
  • The program detects and reports contradictions in genotypic data concerning Mendelian inheritance.

Main Results:

  • Checkfam effectively identifies contradictions in genotypic data.
