Complete a cross between two organisms that are both heterozygous for black fur (bb which is dominant over white fur). use a punnett square to evaluate the possible genotypes. (1) list all the genotypes from your punnett square for the offspring. (2) determine & list the phenotypes that can be produced in the offspring. (3) determine the probability of producing offspring with the bb genotype. (3 points)

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
