Example Question 23 : Genetics And Evolution. Which of the following best describes biological fitness? Possible Answers: Ability to reproduce. Correct answer: Ability to reproduce. Explanation : Biological fitness in the evolutionary sense is only related to fitness in terms to reproduction. Example Question 24 : Genetics And Evolution. Possible Answers: the ability of an organism to run for long periods of time.
Correct answer: the ability of an organism to create offspring. Explanation : The term "fitness" in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring. Example Question 25 : Genetics And Evolution.
Possible Answers: The weight of the iguana. The number of the iguana's offspring who also survive to reproduce. The number of predators the iguana has in its environment. Correct answer: The number of the iguana's offspring who also survive to reproduce.
Explanation : Biological or Darwinian fitness is defined based on the specimen's ability to reproduce and generate viable offspring. Example Question 26 : Genetics And Evolution. Which of the following is an example of an evolutionary advantage? Possible Answers: A black moth that lives near an industrial site that produces a lot of soot. A white rabbit that lives in a snow covered environment. A cheetah that can run faster than the rest of his pack.
A bird with a beak that can crack nuts in an environment where nuts are the main food source. Correct answer: All of these. Explanation : All of the examples given provide an evolutionary advantage. Example Question 27 : Genetics And Evolution. Possible Answers: The fastest male. Correct answer: The most spotted male.
Explanation : The term biological fitness refers to reproductive success and is different than physical fitness. The more likely that an individual is able to survive and live longer to reproduce, the higher is the fitness of that individual.
Thus, it may indicate the relative measure of reproductive success of an organism in passing its gene s to the next generation. It denotes the relative ability of an individual or population to survive, reproduce and propagate genes in an environment.
There are two ways through which fitness can be measured: 1 absolute fitness and 2 relative fitness. See also:. The diversification of several new species from a recent ancestral source, each adapted to utilize or occupy a vacant ad..
