Question | Answer |
---|---|
Heredity Passing of genetic traits from parents to offspring | Probability The possibility that an event will occur in the future |
dominant trait the trait that will show up most often, always covers up any other trait if present | Hybrid An organism that has two different alleles (genes) for a trait, also called heterozygous |
recessive trait the trait that will not show up most often, will be covered up if dominant trait is present | Purebred An organism that always produces offspring with the same form of a trait as the parent, has the same genes for a trait (homozygous) |
Homozygous An organism that has two identical alleles for a trait, means the same as purebred | Heterozygous having two different alleles for a trait, means the same as hybrid |
Gene the genetic instructions for a specific trait | Genotype An organism's genetic makeup, tells exactly what the gene structure is |
Allele Different forms of a gene, can be dominant or recessive | |
Phenotype An organism's physical appearance, or visible traits. |
