WebAnswer (1 of 10): The standard way to detect linkage is to perform a test cross with a double heterozygote. If the genes are not linked, you would expect a 1:1:1:1 phenotypic ratio in the offspring. Any significant deviation from this ratio suggests linkage of the two genes. If you produced an F...
