Topic 9: Change in Population

inherit

• To obtain genetic material from a parent.

• To lose genetic material to a sibling.

• To share genetic traits with a friend.

• To create new genetic material from scratch.

natural selection

• process by which individuals that are better suited to their environment survive and reproduce more than other members of the same species

• a method of breeding plants and animals for desired traits

• the phenomenon where species evolve due to random mutations

• a theory that explains the origin of life on Earth

sexual reproduction

• Reproductive process that involves two parents combining their genetic material to produce offspring that differ from both parents.

• A method of reproduction that involves only one parent and results in genetically identical offspring.

• A process where offspring are produced without the involvement of gametes.

• A reproductive strategy that allows for rapid population growth without genetic variation.

trait

• A specific characteristic that an organism can pass to its offspring through genetic material during reproduction.

• A random mutation that occurs in an organism's DNA.

• An environmental factor that influences an organism's behavior.

• A temporary change in an organism's appearance due to external conditions.

asexual reproduction

• Reproductive process that involves only one parent and produces offspring that are genetically identical to the parent.

• Reproductive process that involves two parents and produces genetically diverse offspring.

• Reproductive process that occurs only in plants and involves the production of seeds.

• Reproductive process that requires external fertilization and results in varied offspring.

generation

• group of organisms that make up a single step in the line of descent from an ancestor

• a period of time in which a group of people are born and live

• the process of producing offspring

• a classification of species based on their evolutionary history

offspring

• New organisms produced through reproduction.

• A type of genetic mutation.

• An environmental factor affecting growth.

• A stage in the life cycle of an organism.

artificial selection

• process by which humans breed only those organisms with desired traits

• a natural process where organisms adapt to their environment

• the random mating of organisms in a population

• a method of genetic engineering to create new species
