Genetics: The study of Heredity (passing of traits from parent to offspring). Chapter 10 Section 1. Mendel’s Experiment. In the mid 19. th. century, a monk named Mendel studied how traits are passed from one generation to another.. Experimented on . garden peas. .. .  green pea plants reproduce sexually (produce gametes). Karyotypes. To find what makes us uniquely human, we have to explore the human genome. . A . genome. is the full set of genetic information that an organism carries in its DNA.. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells. . Other Patterns of Inheritance. Not all genes show a simple pattern of inheritance…. Many genes have more than two alleles. Many traits are controlled by more than one gene. Complete Dominance. Definition: . What you need to know.
