What is the definition of "fitness" in terms of evolution?
Correct answer: D. The ability of an organism to contribute its genes to future generations
- A. The organism's ability to attain resources while in competition with other organisms of its species
- B. The organism's ability to attract the most mates
- C. The organism's health
- D. The ability of an organism to contribute its genes to future generations
Explanation
In terms of evolution, fitness is a measure of how well an organism is able to survive and reproduce in its environment. The more offspring an organism produces, the more likely its genes are to be passed on to the next generation. This means that the ability of an organism to contribute its genes to future generations is the best measure of its fitness.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.

What is in q2 Hardy Weinberg equilibrium?
There existed two varieties of female freshwater Mollusks in which some were streamlined and some had a high bulge. Over the generations, male freshwater Mollusks learned that high bulge favors more production of offspring. So they started preferring to mate with females having high bulge as compared to streamlined. Will this affect Hardy Weinberg Equilibrium in the population?
