This video tutorial introduces the concept of monohybrid cross, explaining its significance in genetics. It covers the test cross method to determine genotypes and provides examples using flower color. The video details the steps to solve monohybrid cross problems, including setting up a Punnett square and calculating genotypic and phenotypic ratios. A sample problem is solved to illustrate these concepts, focusing on plant height as a trait.
