Over the 2nd several years, these hypotheses are remedied because the experts learn more about the sort and you may build from DNA.

Thomas See Morgan shows you to chromosomes bring family genes, setting-up might style for modern genetics. Along the 2nd 2 decades, he and his co-experts at the Columbia School, identify the spot of numerous good fresh fruit travel (Drosophila melanogaster) family genes towards the chromosomes and build the first hereditary linkage chart, creating the usage Drosophila since a model system to review heredity.
