Here is a resource that can make teaching Grade 9 lessons in Biology more interesting:
The Learning Object (LO) using Microsoft PowerPoint on non-Mendelian genetics explains how genotypes of parents influence the blood types of their children. It provides a self-assessment component to foster a deeper understanding of how multiple alleles play a role in predicting the phenotypes of offspring and its probability.
Title of resource:
Curriculum Entry Point:
Grade 9 Biology – Non-Mendelian Genetics
Content standards and competencies under K-12 curriculum guide:
- The learners demonstrate an understanding of the different patterns of inheritance (sex-linked traits, multiple alleles, and incomplete dominance.
- The learners should be able to explain the different patterns of non-Mendelian inheritance
In non-Mendelian genetics, there can be three or more alleles for a single trait that can influence the outcome of the offspring. An example of this is the ABO blood groups. The traits in blood types are influenced by three alleles namely A, B and O as the recessive allele. From these alleles, four possible phenotypes can manifest in the offspring. These phenotypes are expressed as blood types A, B, AB, and O.
Features of the resource:
This resource uses a Learning Object in a Microsoft PowerPoint format. Answers of students are checked by clicking their preferred answers which are hyperlinked to another slide stating whether their response is correct or not. Correct responses are hyperlinked to slides that provide information about the correct answer.
Questions to Teachers:
- How does the use of Learning Objects help students understand the concepts of Multiple alleles?
- How does the content of this LO (learning object) influence the way they make a summative and formative assessment in their classes
