Learners explore genetics through various hands-on activities. In this biology instructional activity, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic...

Learners describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Pupils extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.
