Why do we resemble our parents?

Genetic information is carried in DNA.

DNA is arranged into chromosomes.

A gene is a section of DNA.

SEXUAL REPRODUCTION

Offspring receive genetic information from both parents.

Different combinations produce variation.

ASEXUAL REPRODUCTION

One parent; no joining of sex cells.

Offspring are usually genetically identical.

Many characteristics are influenced by both genes and environment.

The purple-flowered offspring shown is one possible outcome.
