Heritable Traits

Traits that are passed from parents to offspring through genes.

Examples of Heritable Traits

Eye color, hair color, and certain diseases.

Non-Heritable Traits

Traits that are not passed down genetically and result from environmental factors or individual experiences.

Examples of Non-Heritable Traits

Language spoken, favorite hobbies, and acquired skills.

Asexual Reproduction

Reproduction involving a single parent organism, producing offspring genetically identical to itself.

Methods of Asexual Reproduction

Budding, binary fission, vegetative propagation, and spore production.

Advantages of Asexual Reproduction

Quick reproduction, no mate needed, and rapid population growth.

Disadvantages of Asexual Reproduction

Lack of genetic diversity can make populations vulnerable to diseases and environmental changes.

Sexual Reproduction

Involves two parent organisms contributing genetic material to produce genetically varied offspring.

Examples of Sexual Reproduction

Mammals, birds, and flowering plants.

Advantages of Sexual Reproduction

Greater genetic diversity, enhancing survival and adaptability.

Disadvantages of Sexual Reproduction

Requires a mate, slower population growth, and more energy and resources needed for mating and rearing young.
