Question

Three recessive traits in garden pea plants are as follows: yellow pods are recessive to green pods, bluish green seedlings are recessive to green seedlings, creeper (a plant that cannot stand up) is recessive to normal.  A true breeding normal plant with green pods and green seedlings was crossed to a creeper with yellow pods and bluish green seedlings.  The F1 plants were then crossed to creepers with yellow pods and bluish green seedlings.  The following results were obtained for the F2 offspring:

 

            2059 green pods, green seedlings, normal

            151 green pods, green seedlings, creeper

            281 green pods, bluish green seedlings, normal

            15 green pods, bluish green seedlings, creeper

            2041 yellow pods, bluish green seedlings, creeper

            157 yellow pods, bluish green seedlings, normal

            282 yellow pods, green seedlings, creeper

            11 yellow pods green seedlings, normal

 

Construct a genetic map that shows the map distances between these 3 genes.
