You are looking at the color of feathers in ducks and find that Green feathers (G) are dominant to yellow feathers (g). However, a second gene, H, controls whether the color will be expressed in the feathers. If the duck is hh, the duck will always be white, because the pigment does not go into feathers. What ratio of phenotypes in the progeny would you expect following a dihybrid cross

TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.

A biotech company had discovered in animal experiments that drug A might be helpful in treating insomnia (inability to sleep). After it found no apparent drug side effects in humans, the company tested the effects of the drug in 48 individuals. The best stated hypothesis for the drug trial is

An 8-mer oligopeptide has the following amino acids:
A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i.e. ABCDEFGH.
