One true-breeding line of mice is obese and dark, and the other true-breeding line is lean and light. Dark is dominant to light, but obese and lean exhibit incomplete dominance. The two genes involved are on separate chromosomes. What proportion of F2 offspring resulting from a cross of two F1 progeny from a cross of the two lines described above should be dark and intermediate between obese and lean?

Who discovered tuberculosis bacteria?

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
