In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If two red-eyed heterozygous

flies (Rr) mate together, what are the possible genotypes of their offspring? (Hint: You many want to complete a Punnett square.) RR and Rr Rr only RR and rr RR, Rr, and rr

So here we have two heterozygous organisms that will mate. You can put them into a Punnet square, just to be sure of your answers and to find all possible genotypes : 

      R      r
R  RR   Rr
r   Rr     rr

So you have RR, Rr and rr as your possible genotypes.

What would happen to the proton gradient and ATP production after a drug has poisoned the enzyme that combines acetyl CoA and ox
Dmitriy789 [7]

Answer:

The proton gradient becomes weaker

Reduction in the amount of ATP produced.

Explanation:

The combination of acetyl CoA and oxaloacetate drives the formation of nicotinamide adenine dinucleotide + hydrogen (NADH). Poisoning the enzyme that aids this combination will result to lesser production of NADH which would lead to weakening the proton gradient and the reduction in the amount of adenosine triphosphate (ATP) produced.
