Question 1

Natural selection

Answer 1

Natural selection is the process where organisms with beneficial traits are more likely to survive and reproduce, passing those traits to their offspring, leading to the gradual evolution of populations over time

Question 2

Genetic Drift

Answer 2

andom fluctuations in the frequency of different gene variants (alleles) within a population over generations

Question 3

Variation

Answer 3

the differences in characteristics (traits) among individuals within a population, or between different populations or species

Question 4

Fitness

Answer 4

an organism’s ability to survive and reproduce in a given environment, ultimately contributing to its ability to pass on its genes to the next generation

Question 5

Differential reproduction

Answer 5

the concept that not all individuals within a population reproduce at the same rate; some leave more offspring than others

Question 6

Adaptation

Answer 6

the evolutionary process where an organism’s traits become better suited to its environment, increasing its chances of survival and reproduction
