During meiosis some of the genes inherited from your mother get swapped onto the strand of
dna you inherited from your father, and vice versa. this event is called crossing over.
which outcome is the ultimate result of crossing over?
disintegration of the nuclear membrane
o decreased likelihood of twins
increase in the variability of phenotypes
o a smaller number of chromosomes

The outcome resulting from crossing over is increase in the variability of phenotypes.

Explanation:

The non-sister chromatids tend to exchange some of the segments of chromosomes during  the process of meiosis. This phenomenon is termed as crossing over or recombination.

Due to crossing over, a variety of different combinations are achieved in the genes. Hence, crossing over results in increased number of variability of phenotypes. The wide variety of genetic diversity produced is due to this phenomenon i.e crossing over or recombination.

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

answer; the above statement is (true);
