In the late 1920s, a mutation occurred in many silver

fox farms around the world. The fox farms that sold
expensive furs were proud of the quality of their furs,
and each advertised that it had the best, purest breed
of all the fox farms. The new mutations produced a
“platinum” coat pattern that was commercially
desirable, so the farms crossed them to get more. The
results of their breeding experiments were as
follows: (1) silver x silver >>> all silver offspring;
(2) silver x platinum >>> equal numbers of silver
and platinum; (3) platinum x platinum >>> two
platinum for each silver offspring. Explain. What will be an ideal response?


Answer: PP (silver), Pp (platinum), pp (lethal)
