In the video "Learn Biology: How to Draw a Punnett Square", you are taught about dominant and recessive genes, and how to set up and make your own punnett square for future genetics equations. You also learn about the genotypes and phenotypes after completing your punnett square.
During the video "Pedigree Charts", you will learn how to read a pedigree chart and how they are set up. Knowing how to set up a pedigree chart is an important factor when working with genetics. Scientists work with pedigree charts to look at a family history on a certain trait, and they work with punnett squares to look at possible offspring traits. With a pedigree chart, you must infer about the gene pairs for each based on their parents and what trait they hold. This is all taught throughout this quick and informational video.
