Use Mendel's laws of segregation and independent assortment to analyze patterns of inheritance.
Subject Area: Science
Grade: 912
Body of Knowledge: Life Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
Standard: Heredity and Reproduction -

A. DNA stores and transmits genetic information. Genes are sets of instructions encoded in the structure of DNA.

B. Genetic information is passed from generation to generation by DNA in all organisms and accounts for similarities in related individuals.

C. Manipulation of DNA in organisms has led to commercial production of biological molecules on a large scale and genetically modified organisms.

D. Reproduction is characteristic of living things and is essential for the survival of species.

TEST ITEM SPECIFICATIONS

    Also Assesses:

    SC.912.L.16.2 Discuss observed inheritance patterns caused by various modes of inheritance, including dominant, recessive, codominant, sex-linked, polygenic, and multiple alleles.

  • Clarification :

    Students will use Mendel’s laws of segregation and independent assortment to analyze patterns of inheritance.

    Students will identify, analyze, and/or predict inheritance patterns caused by various modes of inheritance.

  • Content Limits :

    Items referring to general dominant and recessive traits may address but will not assess the P and F1 generations.

    Items addressing dihybrid crosses or patterns that include codominance, incomplete dominance, multiple alleles, sex-linkage, or polygenic inheritance may assess the P and F1 generations.

  • Stimulus Attributes :

    Inheritance outcomes may be expressed in percent, ratios, or fractions.

    Scenarios may refer to codominance or incomplete dominance but not both codominance and incomplete dominance.

    Punnett squares may be used to predict outcomes of a cross.

  • Response Attributes :
    Options may include codominance or incomplete dominance but not both.
  • Prior Knowledge :
    Items may require the student to apply scientific knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge of SC.7.L.16.1 and SC.7.L.16.2.
