This is an example of CONDOMINANCY.
Condominancy is said to occur when two different alleles are combined together to form a different allele, in which the alleles are expressed equally and none of them is dominant. In the example given above, the black rat population mated with the white rat population to produce offspring that are grey in colour. Thus, the white and the black colour of the parents are not dominant, but are equally expressed to give gray colour.

<u>Answer:</u>
- few nutrients
- high pressure
- low temperatures
<u>Explanation:</u>
1. Few nutrients: open-ocean zone is located way far from the land, which is the main source of the essential nutrients.
2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.
3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.
4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.
5. Low temperatures: the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.
