What do the letters on the inside of the puunnett squre stand for

The possible genotypes of their children

Explanation:

A punnet square can be described as a diagram which  illustrates the outcomes of a cross. The letters on the outside of a punnet square depict the genotype of the parents whereas the letters on the inside depict the genotype of the children.

For example consider the following punnet square:

        A          a

A    AA       Aa

a     Aa      aa

In the following punnet square, Aa and Aa are the genotypes of the parents.

the children would have the probability of having the following genotypes: AA, Aa, Aa, aa

answer: - few nutrients

high pressure

low temperatures

explanation: 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
