Question
3) Recombination rates among eight loci in lima beans were estimated in a set of two-point crosses and are given below. A statistical test revealed some of the recombinant frequencies to be significantly different than 50% and are indicated in bold. Draw a genetic map for the different linkage groups.

Explanation / Answer
since, recombination frequency of D, WL, R, S, L1, Ms, C are all high with G it can be said that G is placed on a different chromosome.
since, frequency of D is low with Wl and R they are very close to D. similarly, S and L are close and so are Ms and C.
the order of genes is
Loci: R (38.0) Wl(2.1) D (52.4) S (26.9) L (48.2) Ms (14.7) C
loci: G
