How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Controlled variable. Something made of two or more parts working together to perform a function A characteristic that an organism can pass on to its offspring. 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. 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. When matter can enter and leave a system. 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). A weaker form of a gene that is hidden when combined with a dominant allele. (lower case) A stronger form of a gene that, when present, covers up the appearance of the recessive allele. (capital letter) The form of a trait that is displayed in an organism (what you see). A plant that produces offspring with the same form of a trait when self pollinated When matter or energy moves inside of a system The set of traits an organism receives from its parents A segment or unit of DNA that determines traits (heredity) Different forms of the same trait (gene)
