In the plant Arabidopsis, the loci for pod length (L, long; l, short) and fruit hairs (H, hairy; h, smooth) are linked 16 map units apart on the same chromosome. The following crosses were made:

(i) L H/L H X l h/l h = F1

(ii) L h/L h X l H/l H = F1

If the F1’s from (i) and (ii) are crossed, what proportion of the progeny are expected to l h/l h?
