โœฆ Synopsis


Two-point linkage analyses yielded correct identification of linkage groups and good estimates of recombination frequencies in both males and females. Additional analyses compared various family structures for the total number of typed individuals necessary to detect linkage. Results suggest that for codominant markers with moderate recombination frequency, pedigrees may not provide substantial savings over nuclear families.

A three-ste;, procedure was employed to analyze the workshop data. Pairwise lod scores were computed using LIPED and were utilized for estimating the recombination frequencies and thereby the order among loci. This approach proved sugcient to identify accurately and to order the two linkage groups.

A method to construct genetic maps using two-point lod tables was applied to the simulated pedigree data. The analysis provided the correct map order and distances between markers with remarkable accuracy. The methodology is discussed.

For each pair of loci among the four loci in a linkage group, a two-point analysis was performed. It consisted of estimating means, variances, and correlation of male and female recombination fractions and approximating the joint likelihood by a bivariate normal density. The painvise results were as
