How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Controlled variable. A weaker form of a gene that is hidden when combined with a dominant allele. (lower case) When matter or energy moves inside of a system A segment or unit of DNA that determines traits (heredity) When matter cannot enter or leave a system. The set of traits an organism receives from its parents A plant that produces offspring with the same form of a trait when self pollinated A stronger form of a gene that, when present, covers up the appearance of the recessive allele. (capital letter) Something made of two or more parts working together to perform a function An Austrian monk who studied pea plants that was known as the "Father of Genetics" When matter can enter and leave a system. A characteristic that an organism can pass on to its offspring. Different forms of the same trait (gene) The form of a trait that is displayed in an organism (what you see). How does the number of sickle cells in a human body effect the amount of oxygen that is received by cells. dependent variable? How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Independent variable. An organisms genotype shows the actual alleles of the gene.
