Genetics Vocabulary Challenge

This tutorial covers the basics of genotypes, including how to identify heterozygous and homozygous genotypes, and the concepts of dominant and recessive traits. It explains how genotypes affect phenotypes, using eye color as an example. The video provides a detailed guide on creating and analyzing Punnett squares to predict genetic outcomes, including calculating genotype and phenotype probabilities.
