Proteins they make the trait. An organism that has the same allele for a trait on each chromosome pair Variable that is changed in an experiment (the cause) The variable that is kept the same in an experiment The allele that gets covered up by the stronger allele. This allele is weaker and may not be seen visually in a trait. The physical appearance of a trait. Color, shape, etc. If/Then (Cause/Effect) statement that answers the question before an experiment The code that both alleles encode for on each chromosome pair Data from an experiment The allele that covers up or overpowers the other allele. This is the allele that is seen visually in the trait. Each person has two gene "variant copies" for every trait. One of these genes variants is found on each chromosome
