Allele
A different form of a gene.
Gene
A segment of DNA that carries instruction of a trait.
Homozygous
Having two identical versions of a gene (one from each parent).
Recessive Allele
A version of a gene that only shows its traits if an organism has two copies of it.
Protein Synthesis
The process by which cells make proteins using instructions from DNA.
Anemia
A condition where the blood doesn't have enough healthy red blood cell to carry oxygen.
Genotype
The genetic make up of an organism (the alleles it has)
Inheritance
The process by which traits are passed from parents to offspring.
Sickle Cell Anemia
A genetic blood disorder where red blood cells are abnormally shaped causing them to block flow and carry less oxygen.
DNA
The molecule that store an organism's genetic information.
Carrier
A person who has one copy of a gene for a trait or disorder but does not show symptoms.
Haplotype
A group of genes or DNA variation that are inherited together from one parent.
Mutation
A change in DNA the molecule that carries instructions for how living things grow and work.
Sickle Cell Trait
When a person carries one normal gene and one sickle cell gene usually without severe symptoms.
RNA
A molecule that carries genetic instructions from DNA and helps make proteins.
Codominance
A pattern of inheritance where both alleles are fully expressed at the same time.
Hemoglobin
A protein in red blood cell that carries oxygen around the body
Pedigree Chart
A pedigree chart is a family tree that shows how a trait is passed down.
Single-Point Mutation
A change in just one nucleotide in a gene
Amino Acid
A building block of protein.
Dominant Allele
An Allele that shows its trait even when only one copy is present.
Heterozygous
Having two different versions of a gene (one from each parent).
Phenotype
The visible physical traits or characteristics of an organism.
Punnett
A chart used to predict the possible genetic outcomes of a cross between parents.
Chromosomes
Structures in cells that carry genetic information (DNA that determines traits).
