Genetics, Heredity and Variation · Semester 1

Sex-Linked Inheritance

Students will investigate inheritance patterns of genes located on sex chromosomes.

Key Questions

  1. Explain why certain genetic disorders are more prevalent in one sex than the other.
  2. Predict the inheritance of sex-linked traits using Punnett squares.
  3. Analyze the implications of sex-linked inheritance for genetic counseling.

Introduction to Heredity

Students will define key genetic terms and explore the basic principles of inheritance.

2 methodologies

Mendelian Genetics: Monohybrid Crosses

Students will apply Mendel's laws of segregation to predict inheritance patterns in monohybrid crosses.

2 methodologies

Mendelian Genetics: Dihybrid Crosses

Students will apply Mendel's law of independent assortment to predict inheritance patterns in dihybrid crosses.

2 methodologies

Non-Mendelian Inheritance: Beyond Simple Dominance

Students will explore patterns of inheritance such as incomplete dominance, codominance, and multiple alleles.

2 methodologies

Chromosomes and Genes

Students will understand that chromosomes carry genes and explore the basic relationship between them.
