The physical trait that is displayed based on an individual’s genotype

-Both alleles are the same – either both dominant or both recessive

Having one dominant allele and one recessive allele for a trait

Making changes to the DNA sequence of an organism -

A genetic trait that has more than 3 or more alleles, with at least two being dominant at the same time

A type of trait that is displayed phenotypically if an individual has at least one dominant allele

A type of trait that is only shown when all/both of an individual’s alleles are the same

A similarity that still exists between different species that have a common ancestor – evidence for evolution.

Changes in the DNA makeup of a population due to random chance (usually occurs in small populations)

A theory that states that eukaryotes originated from prokaryotes living inside other prokaryotic cells, forming mitochondria and chloroplasts.

A characteristic of an organism that helps it survive in its environment.

Eukaryotic, multicellular organisms with cell walls and chloroplasts. Photosynthesis for energy.

Eukaryotic microorganisms with many different structures – most are unicellular.

Genetic differences among organisms of the same species or of different species in a community.

A trait that an individual organism has that is different from others of the species and that passes down genetically

The places where different populations have lived on earth throughout geologic history – evidence of evolution.

Any species from which two or more organisms evolved – it is an ancestor of both species.
