Need to help your students understand the vocabulary related to genetics and chromosomes? This interactive vocabulary activity helps them build and review the vocabulary needed to understand these concepts. These vocabulary dominoes help students to work collaboratively with a group to discuss the terms while matching words, definitions, and images. After this activity, students should have a good understanding of the vocabulary needed for mastery of these challenging topics.

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.

7.14A – TSIET define heredity as the passage of genetic instructions from one generation to the next generation.
7.14C – TSIET recognize that inherited traits of individuals are governed in the genetic material found in the genes within chromosomes in the nucleus. (Supporting Standard)
Biology 6A – TSIET identify components of DNA, and describe how information for specifying the traits of an organism is carried in the DNA;
