Every organism requires a set of instructions (genes) for specifying its traits. Heredity is the passage of these instructions from one generation to another.

SCI.7-8.S7-8:40.b: Science

As a result of sexual reproduction, half of an individual's traits come from one parent, half from the other.

SCI.7-8.S7-8:40.c: Science

An inherited trait of an individual can be determined by one or by many genes, and a single gene can influence more than one trait.

Comparing and contrasting the chromosome content of somatic cells and that of sex cells (gametes).

SCI.9-12.S9-12:40.a: Science

Instructions for specified characteristics of an organism are carried in DNA. (NSES) The information passed from parents to offspring is coded in DNA molecules. DNA molecules are long chains linking just four kinds of smaller molecules, whose sequence encodes genetic information.

SCI.9-12.S9-12:40.b: Science

The human body is formed from cells that contain homologous parts two copies of each chromosome.

SCI.9-12.S9-12:40.c: Science

New heritable characteristics can result from new combinations of existing genes or from mutations of genes in reproductive cells.

SCI.9-12.S9-12:40.d.: Science

The sorting and recombination of genes in sexual reproduction results in a great variety of possible gene combinations (Include value of meiosis, but not phases).

SCI.9-12.S9-12:40.d.: Science

Some new gene combinations make little difference, some can produce organisms with new and perhaps enhanced capabilities and some can be deleterious.

SCI.9-12.S9-12:40.d.: Science

Gene mutations can be caused by radiation and chemicals (legal and illegal) and are passed on to offspring when they occur in sex cells.

SCI.9-12.S9-12:40.d.: Science

Inserting, deleting or substituting DNA segments can alter genes.

SCI.9-12.S9-12:40.d.: Science

Changes in DNA (mutations) occur spontaneously at low rates, but can affect the organism in many ways or may go unnoticed.

SCI.9-12.S9-12:40.e: Science

Gene mutations in a cell can result in uncontrolled division called cancer. Exposure of cells to certain chemicals and radiation increases mutations and thus chances of cancer.

SCI.9-12.S9-12:41.1: Science

Diagramming a feedback loop that illustrates how several human body systems work together to restore homeostasis in response to an external stimulus (environmental/behavioral) (e.g., exercise, immune response, fight/flight, stress, drugs, normal cellular metabolism, any nervous system response).

SCI.9-12.S9-12:41.2: Science

Explaining examples of how the human body may be affected by the state of the internal or external environment and by heredity and by life experience (e.g., effects of malnutrition).

SCI.9-12.S9-12:41.3: Science

Using evidence to predict and explain how the effect of various environmental or hereditary factors influence the continuation of the human species (reproductive success) (e.g., anorexia and/or steroid use, radiation/toxic wastes/drug use, mutagenic agents and/or improper diet/obesity).

SCI.9-12.S9-12:41.a: Science

All systems of the body are continually working together (communicating) to maintain balance (homeostasis) by responding to internal and external stimuli, e.g., cell-cell (B and T lymphocyte interaction, neurotransmitter secretion by nerve cells); organ-organ (hormones trigger target cells; motor impulses trigger muscles); system (respiratory/circulatory/excretory system interactions, endocrine/digestive/motor and biochemical responses to stress); external stimuli-organism (hypo/hyperthermia, chemical stimuli affect organs/systems/whole organism; sense reception, nerve response)

SCI.9-12.S9-12:41.b: Science

Human behavior is determined by the state of our internal biochemical environment, our heredity and our life experiences (e.g., innate/learned behaviors).

SCI.9-12.S9-12:41.c: Science

SCI.9-12.S9-12:42.e: Science

The severity of human disease depends upon many factors, such as resistance to disease the virulence of the infecting organism.

SCI.9-12.S9-12:42.f: Science

Justifying a position on the use of technology to influence human embryonic or fetal life.

SCI.9-12.S9-12:43.a: Science

Human development begins with a single cell formed by fusion of egg cell and sperm cell and continues through nine months of further development and growth, similar to the development of other animals with backbones; and differences in an embryo's environment can influence the path of development.

SCI.9-12.S9-12:43.b: Science

During human gestation and development a balance is necessary between brain size and birth size, therefore humans need more time after birth for full development of the brain and nervous system than other vertebrates.

SCI.9-12.S9-12:43.c: Science

The long period of human development is associated with the prominent role of the brain.

SCI.9-12.S9-12:43.d: Science
