Flashcards from Concept 13.1 of Pearson's Campbell Biology, Twelfth Edition.

Heredity (inheritance)

The transmission of traits from one generation to the next

Variation

The differences in genetic outcomes between sons and daughters of parents

Genetics

The study of heredity and inherited variation

Genes

The units of heredity, made up of segments of DNA

Gametes

Reproductive cells in which genes are passed down to the next generation

• Includes sperm and eggs

Somatic cells

All cells of the body except gametes and their precursors, containing 46 chromosomes

Locus

A gene’s specific position along a chromosome

Asexual reproduction

A type of reproduction where a single individual passes all of its genes to its offspring without the fusion of gametes

Clone

An individual or group of genetically identical individuals from the same parent

Sexual reproduction

A type of reproduction where two parents give rise to offspring that have unique combinations of genes inherited from the two parents
