More recently, the integrated map approach has been possible utilizing a greater number of markers resulting in longer map lengths.
The different widths of linkage groups reflect the different map lengths of the corresponding chromosomes and represent thus the recombination frequency of markers on each chromosome.
Instead, recombination ratios were estimated by comparing map lengths.
* Linkage map lengths are the sex-averaged map lengths, calculated by using all the individuals of the pedigree.
Map lengths, number of markers for genetic maps, corrected map lengths and total recombination rates used in study.
The total map lengths were strikingly different between the sexes (the corrected map lengths were 1890.0 cM for female and 1457.0 cM for the male map).
First, the genome-wide male and female total map lengths were compared.
These map lengths were both significantly smaller than that reported for the NL94 population.
Total map lengths (Haldane) were 615 cM, 690 cM, 428 cM and 276 cM, respectively.
Several factors might contribute to variations in map lengths for Antirrhinum and might differ between chromosomes.
The map lengths and marker densities were positively correlated among the populations (r = 0.73).
