dominance
Mendel identified the trait of dominance in certain genes.
Mendel found that certain forms of genes were dominant to other forms of genes. This means that when an organism has two different forms of a gene, one form will be expressed over the other in determining the trait it controls.
Mendel's Law Of Segregation
Mendel identified the trait of inheritance through his experiments with pea plants, discovering the principles of dominant and recessive traits. He found that certain genes were responsible for specific traits, which were passed down from parents to offspring according to predictable patterns.
Mendel believed in the principle of separation. This occurs during the formation of gametes and the pair of genes that control a trait separate.
Hybrid
invisible "factors" - now called genes.
One gene controlled one trait within Mendel's study, but the sickle cell anemia effects more than one trait.
Punnett squares go beyond Mendel's research by allowing for the prediction of inheritance patterns for multiple genes simultaneously. While Mendel focused on the inheritance of one trait at a time, Punnett squares can be used to determine the probabilities of various trait combinations in offspring. This tool enhances our understanding of genetic inheritance by illustrating the complex interactions between different genes.
