Heredity: Inheritance and Variation of Traits

Performance Expectations

LS3 help students formulate answers to the questions: “How are characteristics of one generation passed to the next? How can individuals of the same species and even siblings have different characteristics?” The LS3 Disciplinary Core Idea from the NRC Framework includes two subideas: Inheritance of Traits, and Variation of Traits. Students are able to ask questions, make and defend a claim, and use concepts of probability to explain the genetic variation in a population. Students demonstrate understanding of why individuals of the same species vary in how they look, function, and behave. Students can explain the mechanisms of genetic inheritance and describe the environmental and genetic causes of gene mutation and the alteration of gene expression. Crosscutting concepts of patterns and cause and effect are called out as organizing concepts for these core ideas.

Calculation Method for DCI

Disciplinary Core Ideas are larger groups of related Performance Expectations. So the Disciplinary Core Idea Grade is a calculation of all the related Performance Expectations. So click on the Performance Expectation name below each Disciplinary Core Idea to access the learning targets and proficiency scales for each Disciplinary Core Idea's related Performance Expectations.

SCI-HS.LS3.01

Life Science LogoHigh School (SCI) Life Science Standards
[LS3] Heredity: Inheritance and Variation of Traits

SCI-HS.LS3.01 Construct an explanation to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

Clarification Statement: Emphasis should be on traits including completely dominant, codominant, incompletely dominant, and sexlinked traits. Examples can include pedigrees, karyotypes, genetic disorders, Punnett squares, dihybrid crosses
Disciplinary Core Ideas
LS1.A: Structure and Function -All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins.
LS3.A: Inheritance of Traits -DNA make up genes that are sections on chromosomes which are the instructions for forming individual characteristics (traits). All cells of an organism have the same genetic content. Gene expression is regulated in different ways.

SCI-HS.LS3.02

Life Science LogoHigh School (SCI) Life Science Standards
[LS3] Heredity: Inheritance and Variation of Traits

SCI-HS.LS3.02 Make and defend a claim based on evidence that inheritable genetic variations result from various factors.

Clarification Statement: Emphasis is on (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. Emphasis is also on using data to support arguments for the way variation occurs
Disciplinary Core Ideas
LS3.B: Variation of Traits -Sexual reproduction (meiosis) creates variation through crossing over and independent assortment. Mutations may occur during DNA replication resulting in genetic variation or due to environmental factors. The variation and distribution of traits observed depends on both genetic and environmental factors.

[LS3] Heredity: Inheritance and Variation of Traits

SCI-HS.LS3.03 Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

Clarification Statement: Emphasis is on distribution and variation of traits in a population and the use of mathematics to describe the distribution. Examples can include calculations of frequencies in Punnett squares, graphical representation
