Availability of food, predators, and the number of species living in an area affect a species' ____________.
What is survival?
200
The combination of genetic makeup and the environment's effect on that makeup.
What is phenotype?
200
The study of heredity.
What is genetics?
200
The process in which DNA changes result in new alleles.
What is mutation?
200
A British biologist who studied the diversity of living things while sailing aboard the HMS Beagle. He created the theory of evolution by natural selection.
Who is Charles Darwin?

Clown fish can change this about themselves in order to maintain a high level of reproduction.
What is gender?
300
A part of the DNA code on a chromosome.
What is gene?
300
An allele that will show its effect on the phenotype only when two of the them fora train are present in the genotype.
What is recessive?
300
Organisms that are better adapted to an environment survive and reproduce at a greater rate than organisms that are not.
What is natural selection?
300
A group of people who developed maize from a wild grass called teosinte. By carefully selecting and breeding individual plants with desired traits, they developed modern corn.
Who are the Native Americans?

Gregor Mendel developed principles of genetics by experimenting with _________________.

400
The genes that an organism has; its genetic makeup.
What is genotype?
400
A chart that can help you understand and make genetic predictions.
What is Punnett square?
400
The production of several species from one ancestral species.
What is adaptive radiation?
400
The first researcher to use numbers to describe the results of genetics experiments.
Who is Gregor Mendel?
400
Temperature, rainfall, fire, elevation, volcanic eruptions, periodic flooding, and pollution are examples of what type of influences?
What are nonliving?
500
The type of allele that will show its effect on the phenotype whenever present in the genotype.
What is dominant?
500
The different forms of a gene.
What is allele?
500
Each parent passes only one allele for a train to its offspring.
What is segregation?
500
A lesser known British biologist who hypothesized about how so many living things came to exist on Earth. He studied in the East Indies.
Who is Alfred Russell Wallace?
500
This principle states that the alleles for one trait do not influence the alleles of another trait.
