Mechanisms of Evolution Quiz

The process where members of one sex choose mates based on specific features, such as bright colors or elaborate displays.

Changes in allele frequencies within a population due to random chance, particularly impactful in smaller populations.

The creation of new genetic variations, often in non-coding regions of DNA, leading to changes in the genetic makeup of organisms.

The process of genetic exchange between populations, leading to increased similarity in their allele frequencies.

A statement proposing no effect or relationship between variables, often used as a starting point in scientific research.

The systematic study of human societies, cultures, and their development, encompassing various aspects like archaeology, linguistics, and cultural anthropology.

A field of study focusing on stable changes in gene expression during development, often influenced by environmental factors, without alterations in the underlying DNA sequence.

Organisms characterized by the presence of a membrane-bound nucleus and other internal organelles, such as mitochondria and Golgi apparatus.

Organisms lacking a membrane-bound nucleus and other internal organelles, simpler in structure compared to eukaryotes.

The powerhouse of the cell, responsible for generating energy (ATP) through cellular respiration.

Body cells, all cells except gametes, that divide via mitosis to produce identical daughter cells.

Cells containing half the number of chromosomes compared to a diploid cell, crucial for sexual reproduction.

Cellular organelles responsible for protein synthesis, translating the genetic code from mRNA into amino acid sequences to build proteins.
