Genetics and Heredity

7th Grade•30 minutes•7-ls-1-6

Learning Objective

I can define genetics and heredity and explain how they are related by using the video to answer questions with at least 80% accuracy.

Genes are individualized sections of DNA on the chromosomes of cells and carry instructions for making molecules called proteins.

An organism’s genotype is their complete collection of alleles, while the phenotype describes the traits that we can observe.

A Punnett square can be used to map out the odds of allele combinations that offspring may inherit from their parents.

This lesson includes 3 practice questions to reinforce learning.
