7th Grade (SCI) Life Science Standards [LS3] Heredity: Inheritance and Variation of Traits
SCI-MS.LS3.01 Develop and use a model to describe why structural changes to genes
(mutations) located on chromosomes may affect proteins and may result in
harmful, beneficial, or neutral effects to the structure and function of the
organism.
Clarification Statement: Emphasis is on conceptual understanding that changes in genetic material may result in making different
proteins. Disciplinary Core Ideas LS3.A: Inheritance of Traits
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.
LS3.B: Variation of Traits
Genetic information can be altered because of
mutations. Though rare, mutations may result
in changes to the structure and function of
proteins. Some changes are beneficial, others
harmful, and some neutral to the organism.
