Heredity is the process by which traits are passed from parents to offspring.

Alleles are different versions of a gene that exist in pairs, one inherited from each parent.

A trait is a characteristic or feature of an organism, such as eye color or height.

A gene is a segment of DNA that contains the instructions for building a specific protein, which influences a trait.

A chromosome is a long strand of DNA that contains many genes; humans have 23 pairs of chromosomes.

DNA carries the genetic information that is passed from parents to offspring, determining inherited traits.

Dominant alleles express their traits even if only one copy is present, while recessive alleles require two copies to express their traits.

A generation refers to all the offspring born and living at about the same time, often used to study inheritance patterns.

An inherited trait is a characteristic that is passed down from parents to their offspring through genes.

Eye color is an example of an inherited trait in animals.
