Explanation:
The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour. 
Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.
Crossing CB CB × CW CW,
100% CB CW - tan-coloured birds
 
        
             
        
        
        
The factor that does not help determine whether a volcanic eruption will be explosive or relatively quiet is the composition of the lava.
On the other hand, the composition of the magma, the temperature of the magma, and the amount of dissolved gases in the magma are quite important for determining this.
        
                    
             
        
        
        
NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.
