A Graphic used to help predict the possibility
of different gametes

Punnett squares and probability.

A Punnett square can be used to predict genotype and phenotypes of offspring from genetic crosses.

Each parent produces one kind of gamete, resulting in an F{1} generation with a dominant yellow phenotype and the genotype Yy

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
