SC4-15LW
explains how new biological evidence changes people’s understanding of the world
LW3 Advances in scientific understanding often rely on developments in technology, and
technological advances are often linked to scientific discoveries. (ACSHE158, ACSHE192)

chromosomes
□
5LW3d. outline how the Watson-Crick model of DNA explains: the exact
replication of DNA changes in genes (mutation)

homozygous and heterozygous; and dominant and recessive
The father of genetics Oxford pg 22
Introduce the fundamentals and key terminology of basic genetics, including the
laws of segregation and independent assortment.
First-hand investigation(s): DNA Translation and DNA mutations 10.3.4
Checkpoint 1.2
Complete questions as homework, a mid-topic test or as a class activity. Use
