Maps can be transformed using methods like map, where, and addAll. main.dart void main() { var original = {'a': 1, 'b': 2, 'c': 3}; // Transform values var squared = original.map((key, value) => MapEntry(key, value * value)); // Filter entries var filtered = Map....

However, modern sequencing methods and increasing marker density have reduced the utility of these functions in linkage map reconstruction; the probability of multiple crossovers between closely positioned adjacent loci is negligible and all mapping functions yield essentially the same result, r = d...
