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?

In a testcross of an individual heterozygous for each of three linked genes, the most frequent classes of progeny were A B c/a b c and a b C/a b c, and the least frequent classes were A B C/a b c and a b c/a b c. what is the order of the genes?

#Unit 8. Inheritance Biology
In Drosophila melanogaster, black body (b) is recessive to gray body (B), purple eyes (pr) are recessive to red eyes (PR), and vestigial wings (vg) are recessive to normal wings (VG). The loci coding for these traits are linked, with the following map distances
The interference among these genes is 0.5. Pure line breeding cross Gray body, Red eye, normal wings with black body, purple eye, vestigial wings. If heterozygous female for all loci were allowed test cross, the of progeny with gray body, purple eye and vestigial wings out of 1400?
