Mapping Genes
4. Genetic Mapping and Linkage / Mapping Genes / Problem 1
In a study of a certain plant species, researchers have identified two genes, G and H, located on the same chromosome. A dihybrid plant that is heterozygous for both genes (GgHh) is crossed with a homozygous recessive plant (gghh). The following offspring were obtained:
250 GgHh
50 ggHh
50 Gghh
250 gghh
Using this information, which of the following gives the correct genetic map?
