How to create a chromosome map from crossover frequencies

During meiosis, the two chromosomes in each homologous pair exchange segments, through a process called crossing over. This process of crossing over and the resulting recombination, (exchange of gene alleles across the chromosomes in a pair) enables us to reason about genetic mapping - that is, about the order of genes on a chromosome and the distances among the genes. #chromosomes #genes #alleles #crossingover #geneMapping #chromosomeMapping #genetics
