Definition


A change in genetic information caused by a chance in the sequence of DNA


Evolution caused by random events


Competition between two or more individuals of the same species


Any trait that can be passed on to subsequent generations that increases the organism’s ability to survive in its environment and reproduce


Exhibited by individuals within a group that potentially reduces the fitness of that individual but enhances the fitness of other members of the group.

Competition between two or more individuals of different species


A group of organisms that can interbreed and produce fertile offspring


A large-scale dying off of a vast number of species in relatively short geological time

Answer 1

Answer: Definitions

Step-by-step explanation:

Mutation: A change in genetic information caused by a chance in the sequence of DNA.

Genetic Drift: Evolution caused by random events.

Intraspecific competition: Competition between two or more individuals of the same species.

Adaptation: Any trait that can be passed on to subsequent generations that increases the organism’s ability to survive in its environment and reproduce.

Altruistic Behavior: Exhibited by individuals within a group that potentially reduces the fitness of that individual but enhances the fitness of other members of the group.

Interspecific competition: Competition between two or more individuals of different species.

Species: A group of organisms that can interbreed and produce fertile offspring.

Mass extinction: A large-scale dying off of a vast number of species in relatively short geological time.
