Genotype, Phenotype and Punnett Squares Made EASY!

The video tutorial provides an understanding of genotype and phenotype, explaining how genetic makeup (genotype) translates into physical traits (phenotype). It introduces the Punnett square, a tool for predicting genetic outcomes, and demonstrates its use through examples involving pea plants. The tutorial covers the concepts of dominant and recessive traits, homozygous and heterozygous genotypes, and explains how to conduct genetic crosses. The video concludes with a summary of monohybrid crosses and a preview of dihybrid crosses.
