Why We Made This:

• We created this visual guide to help individuals understand and retain critical developmental milestones and genetic concepts. Many of us can struggle to connect physical, cognitive, social-emotional, and language milestones with the underlying genetics that influence development and disorders. This guide brings clarity through simple explanations, engaging visuals, and real-world examples.

Learning Objectives:

• Identify key physical, cognitive, social-emotional, and language milestones from birth to 24 months.

• Understand how dominant and recessive genes influence inherited traits.

• Explain the three types of genotype-environment correlations: passive, evocative, and active.

• Recognize examples of how genes and environments interact to shape development.

• Distinguish between autosomal, X-linked, and chromosomal genetic disorders.

• Describe why males and females assigned at birth are affected differently by X-linked disorders.

• Identify common genetic disorders such as Down syndrome, Fragile X syndrome, and Huntington’s disease.
