Chromosomes, Part II

Next Generation Standards

MS-LS3-4(MA) is not included in the Next Generation Standards.

Massachusetts Standards

8.MS-LS3-4(MA) - Develop and use a model to show that sexually reproducing organisms have two of each chromosome in their cell nuclei, and hence two variants (alleles) of each gene that can be the same or different from each other, with one random assortment of each chromosome passed down to offspring from both parents.

Clarification Statement - Examples of models can include Punnett squares, diagrams (e.g., simple pedigrees), and simulations.

Assessment Boundary - State assessment will limit inheritance patterns to dominant-recessive alleles only.
