Draggable item		Corresponding Item
allele		any of several possible forms of a gene
recessive allele		intracellular structure made of the cell's double stranded DNA bound to DNA-binding proteins
heterozygous		an allele that is fully express in the phenotype of a heterozygote
phenotype		the genetic code or trait an individual inherits from their parents that determines their physical traits (phenotypes)
homozygous		an organism that has two different alleles for a trait
dominant allele		an organism that has a pair of identical alleles for a trait
genotype		the observable traits of an individual passed from parent to offspring
chromosome		a genetic trait that is unable to be expressed when a dominant gene is present
