One commonly used tool for estimating linkage disequilibrium in haploid organisms like fungi is PLINK. PLINK is a whole-genome association analysis toolset that provides a variety of functions for analyzing genetic data, including calculating linkage disequilibrium.
To estimate linkage disequilibrium in haploid fungi using PLINK, you would typically need to have genotype data for a set of genetic markers (e.g., SNPs) from your fungal samples. You can then use PLINK to calculate measures of linkage disequilibrium, such as r-squared values, between pairs of markers in your data set.
Another tool that is commonly used for estimating linkage disequilibrium in fungi and other haploid organisms is Haploview. Haploview is a software package that provides various functions for analyzing genetic variation, including calculating linkage disequilibrium and creating LD plots.
Both PLINK and Haploview are widely used and well-documented tools that can be useful for estimating linkage disequilibrium in haploid organisms like fungi. You can find more information about these tools and download them from their respective websites.
