Question

two specific mechanisms of evolution are discussed in this lab. can you distinguish between the following terms?
place the terms in the appropriate blanks to complete the sentences.
artificial selection
mutations
natural selection
evolution
adaptations
the process by which individuals in a population with traits best suited for the current environmental
conditions have the greatest success in survival and reproduction is called, which is one
mechanism of evolution.
favorable traits that are passed from one generation to the next are called.
the process by which desirable traits in organisms are selected by humans with the intent of promoting
the desired trait in the offspring is called.
genetic change in a population over generations is called.
random changes in dna are called

Explanation:

• Mutations: Random changes in DNA are called mutations. Mutations are the source of new genetic variation in a population.
• Evolution: Genetic change in a population over generations is called evolution. It is the mechanism by which species change over time.
• Artificial selection: The process by which desirable traits in organisms are selected by humans with the intent of promoting the desired trait in the offspring is called artificial selection. Humans choose which organisms will breed.
• Adaptations: Favorable traits that are passed from one generation to the next are called adaptations. These traits help organisms survive and reproduce in their environment.
• Natural selection: The process by which individuals in a population with traits best suited for the current environmental conditions have the greatest success in survival and reproduction is called natural selection. It is a key mechanism of evolution.

Answer:

• Random changes in DNA are called mutations.
• Genetic change in a population over generations is called evolution.
• The process by which desirable traits in organisms are selected by humans with the intent of promoting the desired trait in the offspring is called artificial selection.
• Favorable traits that are passed from one generation to the next are called adaptations.
• The process by which individuals in a population with traits best suited for the current environmental conditions have the greatest success in survival and reproduction is called natural selection.
