In fruit flies, red eye color (R) is dominant over brown eye color (r). What percentage of offspring would be expected to have brown eyes if parent one is Rr and parent two is rr?

50% offspring could be expected to be Brown , because both parents have a partial recessive trait , so it’ comes out to be 50% chance of red and the other 50% brown

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
