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