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. |
