When matter or energy moves inside of a system A stronger form of a gene that, when present, covers up the appearance of the recessive allele. (capital letter) How does the number of sickle cells in a human body effect the amount of oxygen that is received by cells. dependent variable? Something made of two or more parts working together to perform a function When matter can enter and leave a system. 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 gets to cells. Independent variable. How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Controlled variable. Different forms of the same trait (gene) Pollen grains containing sperm from the male part of the plant (anther) are carried to the female part of the plant called the ovule (self and cross pollination). The set of traits an organism receives from its parents A characteristic that an organism can pass on to its offspring. A plant that produces offspring with the same form of a trait when self pollinated An Austrian monk who studied pea plants that was known as the "Father of Genetics" An organisms genotype shows the actual alleles of the gene. A weaker form of a gene that is hidden when combined with a dominant allele. (lower case) A segment or unit of DNA that determines traits (heredity)
