Genetics and Heredity

Acquired Traits

• A characteristic inherited from parents.

• A characteristic developed by an organism during its lifetime due to environmental influences.

• A trait that is always beneficial for survival.

• A feature that remains unchanged throughout an organism's life.

Inherited Traits

• Characteristics or features of an organism that are passed down from its parents through genes.

• Randomly acquired features that do not have a genetic basis.

• Traits that are developed through environmental influences only.

• Features that are only present in the offspring of a single parent.

Chromosome

• A thread-like structure within a cell's nucleus that contains DNA that is passed from one generation to the next.

• A type of protein that helps in cell division.

• A small organelle responsible for energy production.

• A liquid substance that fills the cell and holds organelles.

Gene Expression

• Determines how inherited traits appear.

• Is the process of DNA replication.

• Refers to the physical structure of genes.

• Involves the mutation of genetic material.

Heredity

• The process of natural selection.

• The passing of traits from parent to offspring.

• The study of genes and DNA.

• The variation of traits within a population.
