Question

BlackTom AI · Accepted Answer

Consider what sexual reproduction accomplishes in terms of offspring variation and adaptation.
Option 1: Greater genetic variability. This is correct because sexual reproduction combines genetic material from two parents, creating unique combinations of alleles and increasing diversity within the population, which enhances potential adaptation to changing environments.
Option 2: Decreased chances of survival in harsh environments. This is incorrect; the increased genetic variability that results from sex generally improves the ability of a population to withstand harsh conditions, not decrease it.
Option 3: Elimination of all harmful traits. This is a misconception. Sexual reproduction does not automatically eliminate harmful traits; while recombination can separate deleterious alleles from beneficial ones over generations, it does not guarantee removal of all harmful traits in every offspring.
Option 4: Increased uniformity among individuals. This is false because sexual reproduction promotes diversity, not uniformity; offspring are genetically distinct rather than identical to one another or to the parents.
