The Role of Genes in Inheritance and Development

🧬Genes are packets of information that code for specific traits passed on from parents to offspring.

🧪Chromosomes contain DNA wrapped around proteins and determine an organism's genetic information.

💡Chromosome number does not indicate complexity, as different genes are active at different times.

🐸Extracellular signals and environmental conditions can activate or deactivate certain genes.

🔬Different stages of development involve the activation of specific genes, resulting in physical appearances.

What are genes?

—Genes are packets of information that contain the instructions for specific traits an organism expresses.

Where are genes located?

—Genes are located on chromosomes within the nucleus of a cell.

Do all cells in an organism contain the same genetic information?

—Yes, all cells in an organism contain the same genetic information, but not all genes are active at the same time.

What determines when genes are activated or deactivated?

—Genes can be activated or deactivated by extracellular signals and environmental conditions.

How do different stages of development result in physical differences?

—Different stages of development involve the activation of specific genes, resulting in different physical appearances.
