Question
Two genes are found in a chameleon, one for camouflage (dull colors dominant to vibrant colors) and another for muscle strength (strong
dominant to weak), which seem to follow basic Mendelian inheritance patterns. To determine if they are linked, you set up a testcross and got
the following results:
Phenotype
Dull colors; Strong
Dull colors; Weak
Number of Progeny
98
76
Vibrant colors; Strong 72
Vibrant colors; Weak 105
Did you start this experiment with the genes in coupling or repulsion? (Be sure you know how to run the chi-square based off this information as
well!)
O Coupling
O Cannot determine with this information
O Repulsion
