16 individuals in a population of 100 are homozygous recessive for a particular trait (a or a). what percent of the alleles in that population are dominant?

36 individuals

Explanation:

In a 100 persons population, 16 represent the 16% of the total or 0.16 This is the percent of recessive alleles.

You know the formulas and

Where is the percent of recessive alleles and is the percent of dominant alleles.

If then

and because , then and

The percent of dominant alleles in this population is 0.36 or 36%, wich means 36 individuals.

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
