#Unit 8. Inheritance Biology

In a certain diploid plant, the three loci A, B, and C are linked as follows: Assuming 100%   interference, if the plant with genotype ABC/abc is test cross, what proportion of the progeny will be of the genotype a b c/a b c?

#Unit 8. Inheritance Biology

A three point test cross was carried out in Drosophila melanogaster involving three adjacent incomplete link genes A, B and C. arranged in the same order. The distance between A to B is 5 map units (mu) and that between B to C is 10 map. If pure line Drosophila AAbbCC crosses with aaBBcc to produce F1 offspring were allowed to cross with aabbcc result in following offspring genotype?

What is a A, B, C respectively?

#Unit 8. Inheritance Biology

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?
