Introduction:
A change in one or more heritable characteristics of population that occurs from one generation to the next is called evolution.
Answer to Problem 1TY
The correct answer is option (d) evolution.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) evolution. A change in one or more heritable characteristics of population that occurs from one generation to the next is called evolution.evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.So, the correct answer is option (d).
Explanation for incorrect answer:
Option (a) Natural selection. natural selection is natural processwhereorganisms better adapted to their environment tends to survive and produce more offspring.so, this is an incorrect option.
Option (b) Sexual selection. Sexual selection is process where one organism member can choose mate of another sex. So, this is an incorrect answer.
Option (c) population genetics. Population genetics is branch of genetics where genetic varition occur within population.
Option (e) inheritance of acquired characteristics.when organism pass their traits to the offspring which is genetically acquired this is called inheritance of acquired characteristics.

Choose all that apply. (1 or more are correct). founder effect fitness allele frequencies bottleneck effect selective advantage/disadvantage cost/benefitarrow_forwardAccording to the principle of Hardy-Weinberg, which of the following will NOT change the frequencies of genotypes in a population? Select one: Genetic drift Natural selection Mutation Random matingarrow_forward
- natural selection, why is maintaining genetic variation in populations such an important part of species being able to live through environmental changes? Include an examplearrow_forwardWhich of the following is the hypothesis that individuals who possess favorable traits are more likely to survive and reproduce than those who possess less favorable traits? genetic drift gene flow mutation natural selectionarrow_forwardNatural selection results in the adaptation of organisms to the circumstances of their way of life and their environment True or Falsearrow_forward
- An allele with no effect on fitness arises in a population through mutation and increases in frequency due to genetic drift. This is an example of....? Group of answer choices neither evolution or natural selection both evolution and natural selection evolution only natural selection onlyarrow_forwardWhich of the following best explains the phrase “survival of the fittest” in terms of evolution by natural selection? The strongest and fastest individuals will always survive and reproduce more often. The individuals that are the healthiest will always get more resources and survive better. Only individuals that have the most mates will survive with limited resources. The individuals that survive better and reproduce more often will pass their traits on more often.arrow_forwardNatural selection is based on all of the following except individuals who survive longer tend to have more offspring than those who die young genetic variation exists within populations Individuals adapt to their environments and, thereby, evolve populations tend to produce more offspring than the environment can support the best adapted individuals tend to reproduce morearrow_forward

Natural selection Genetic drift Gene flow Phenotypes All of the abovearrow_forwardWhat type of selection occurs when one extreme population phenotype is favored?
