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