Hi! Please complete a genetic cross of two parents BB x bb using a Punnett square Alleles B (dominant) has a fast phenotype and allele b (recessive) has a slow phenotype (B-fast, b-slow).

1. Show me the completed Punnett square with the genotypes and phenotypes in each square

2. Give the genotypic and phenotypic ratios

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

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

option c is the correct answer.
