Chromosome mapping based on chossingover frequencies

Mapping is the construction of a series of chromosome descriptions that depict the position and spacing of unique, identifiable biochemical landmarks, including some genes, that occur on the DNA of chromosomes. 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. The next section provides a brief description of crossing over and recombination. The section that follows introduces the logic that allows us to reason about genetic mapping. #gene #chromosome #chromosomeMapping #geneMapping #chromosomeCrossingover
