Trait: The physical characteristic that is displayed. Example: hair color, height, blood type
Gene: A section of DNA that codes for a protein.
Ex: Proteins are molecules that cause the trait.
Allele: Versions of a trait. Each letter is one allele.
B= brown eyes b= blue eyes
You always get 2 alleles. One from each parent.
Homozygous: Both alleles (letters) are the same.
Ex: BB or bb
Heterozygous: One of each allele Ex: Bb
Dominant: The trait that is visible if the allele is present.
Shown with a capital letter
Recessive: These alleles are hidden if a dominant allele is present. Recessive traits only show up if both alleles are recessive. Shown with a lowercase letter: ex: bb
Genotype: Allele combination in letters ex: Bb
Phenotype: The visible trait: ex: Blue eyes
Autosomal: A trait that is found on chromosomes 1-22. Trait is shown with 2 letters...Ex: AA, Aa, aa
Sex-Linked: A trait that is found on the X-chromsome. Girls have XX and boys have XY. Traits are written as exponents above the X Chromosome (can't show this on weebly...but check your notes). Sex-Linked traits are found more often in boys than girls and pass from the mom to the son.
Pedigree: A diagram showing how traits pass down through generations. It shows the phenotype of an individual.
