In chickens, feathered shanks, A, are dominant to clean, a, and white plumage, B, is dominant to black, b. A feathered-shanked,
white, rose-combed bird was crossed with a clean-shanked, white, walnut combed bird and the following offspring were produced: 2 feathered-shanked, white, rose-combed chicks 3 feathered-shanked, black, pea-combed chicks 1 feathered-shanked, white, single-combed chick 4 clean-shanked, white, walnut-combed chicks 1 clean-shanked, black, single-combed chick 2 clean-shanked, white, rose-combed chicks What are the genotypes of the parents? You must show your work in an orderly fashion. I need to be able to follow your logic in order to earn credit. Option 1: AaBbRrdd and aaBbRrDd Option 2: AaBbRRdd and aaBbRrDd Option 3: AaBbRrdd and aaBbRRDd Option 4: AaBBRrdd and aaBbRrDd More than one of the above may be correct
BioSafety Level (BSL) 3 labs,
perform work with indigenous or exotic agents that may cause serious or
potentially lethal diseases through the inhalation exposure. Biological Safety
Levels (BSL) are a sets of protections assigned to the activities that occur in
specific biological laboratories. BSL protects laboratory workers, the
