In this foldable, students learn that inherited traits of individuals are governed in the genetic
material found in the genes within chromosomes in the nucleus of a cell. Depending on which foldable version you choose, students may dive deeper to recognize that genes carry instructions for making proteins, and it is these proteins that govern the traits (phenotype) of individuals. They will understand chromosomes and that the many, many genes located within them come in pairs, with each biological parent contributing one half of the pair. These chromosomes pairs (also known as homologous pairs) have the genes for a trait in the same location, but each might have different versions of those genes. These different possible versions or forms of the genes are called alleles. Students will know that individuals that have genes with two of the same allele form are referred to as having a homozygous genotype, and ones that have two different alleles in a gene pair have a heterozygous genotype. This foldable is designed to give students the foundational knowledge to further explore basic Mendelian (single-locus) inheritance patterns.

Core Disciplinary Ideas
• LS3.A: Inheritance of Traits
o Genes are located in the chromosomes of cells, with each chromosome pair containing two variants of each of many distinct genes. Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual. Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits.
o Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited.
• LS3.B: Variation of Traits
o In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
