In a new species of moth, the genes for body colour (black, B, is dominant over grey, b), wing size
(normal wing, W, is dominant over vestigial, w) and eye colour (red, R, is dominant over white, r)
are linked. In this species, only one cross-over event has been observed between any two
homologous chromosomes during meiosis. In a cross between BB; ww and bb; WW, 5 % of the
progeny were black with normal wings. In a separate cross between RR; WW and rr; ww, 15 % of
the progeny were red-eyed with vestigial wings. In a third cross between BB; rr and bb; RR, 10 %
of the progeny were black-coloured with red eyes. Which among the following is the correct order
of these three genetic loci?

Explanation:
Linkage Analysis:
- From the given information, we can deduce the order of genetic loci by analyzing the percentage of progeny with specific traits in the three crosses.
- In the first cross, 5% of the progeny were black with normal wings, indicating a crossover event between body color and wing size.
- In the second cross, 15% of the progeny were red-eyed with vestigial wings, suggesting a crossover event between eye color and wing size.
- In the third cross, 10% of the progeny were black-colored with red eyes, indicating a crossover event between body color and eye color.
Conclusion:
- Based on the observations from the crosses, we can determine that the order of genetic loci is Body colour - Eye colour - Wing size.
- Therefore, the correct order of these three genetic loci is Body colour - Eye colour - Wing size, which corresponds to option A.
