Introduction to Punnett Squares and Genetic Inheritance Analysis

The video tutorial explains genetic inheritance using Punnett squares. It defines key terms like genotype and phenotype, and illustrates genetic variation with an example of kittens. The tutorial focuses on monohybrid inheritance, using mice to demonstrate how a single gene affects fur color. It explains how to use a Punnett square to predict genetic outcomes, showing the possible genotypes and phenotypes of offspring. The video concludes with calculating phenotypic ratios and probabilities, emphasizing the likelihood of certain traits appearing in offspring.

How does the combination of alleles in offspring lead to variation in physical characteristics?

What is the expected phenotypic ratio of offspring when two heterozygous black mice breed?
