Meiosis is a key process in the sexual life cycle of eukaryotes and is essential for the survival of eukaryotic organisms. In the process of meiosis, crossing over and
independent assortment are events that occur that allow the genes on the
homologous chromosomes to be randomized. These events result in greater genetic
variation than asexual reproduction or mitosis because it
Is more common in higher order species.
O
Results in a greater number of offspring.

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
