Science focused on describing and characterizing a system without testing causal explanations.

A study where the researcher doesn't manipulate any variables; they simply observe and record.

Similarities in structure/traits among species due to shared ancestry.

A discredited theory stating that parent traits mix and are lost in offspring.

An individual with two different alleles for a particular gene.

An individual with two identical alleles for a particular gene.

A variant form of a gene.

A specific location on a chromosome containing a gene.

A process where information flows from germ cells to somatic cells; somatic cells support and protect germ cells.

The idea that information only flows from germ cells to somatic cells, not vice-versa.

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Natural selection acts on individuals, not species, leading to traits that enhance individual reproductive success, not necessarily species survival.

Populations evolve, not individuals. Evolution occurs through changes in the genetic makeup of a population over time.

Research on the changes in a species over successive generations, describing processes like natural selection and adaptation.

Adhering to ethical principles in academic work, such as avoiding plagiarism and cheating.

A scientific method where information about a specific phenomenon or group is systematically gathered, measured, and recorded.

The tendency of observers to score results differently based on their expectations rather than objectively, potentially skewing experimental data.

A variable that affects the dependent variable but is not part of the factors being experimentally manipulated.

A planned approach to analyzing variables and treatments in an experiment that minimizes biases.

A technique where participants or experimenters are unaware of which treatment group they are in or which treatment group is being observed. Designed to reduce bias.

The repetition of measuring the effect of an experimental treatment on a variable.

Data that is descriptive, rather than numerical (like colors, observations, and attitudes)

The group of males in the experiment that received a high-quality diet.

The group of males in the experiment that received a low-quality diet.
