Question

question: which of the following reduces the fitness of an organism, resulting in no offspring or fewer offspring? answer options: select one of four genetic drift negative mutation in dna intentional alteration of amino acids neutral mutations in dna

Explanation:

• Genetic drift is a random change in allele frequencies, not directly reducing fitness to cause fewer offspring.
• Negative mutation in DNA: A negative (deleterious) mutation affects the organism's ability to survive/reproduce, reducing fitness and offspring number.
• Intentional alteration of amino acids: Not a natural process affecting fitness in the context of evolution, and not a standard term for reducing offspring.
• Neutral mutations in DNA: Have no effect on fitness, so don't reduce offspring.

Answer:

B. Negative mutation in DNA
