QuestionAnswer
heterozygous two different alleles; "hybrid" Tt
homozygous two of the same allele; "purebred;" TT or tt
Dd heterozygous
genotype gene or allele combination; "type-o-gene"
phenotype the way a genotype is expressed; what the organism looks and acts like
allele form of a gene
sex-linked traits located on a sex chromosome
XX female sex chromosomes
XY male sex chromosomes
mutation mistake or change in a gene; an error
homozygous dominant DD; two dominant alleles
homozygous recessive dd; two recessive alleles
genetic recombination arranging genes in a new sequence or order
DNA fingerprint visual representation of DNA fragments; shows a banding pattern that can be used to determine relatedness
gel electrophoresis technique that runs DNA fragments through a gel and separates fragments based on size
gene splicing cutting and inserting genes into new DNA sequences
cloning produces identical genetic copies of an organism
carrier heterozygous; carries the allele that can cause a recessive phenotype
hybrid another term for heterozygous
purebred another term for homozygous
dominant trait the trait that shows; always hides the recessive
recessive trait trait always hidden by the dominant; only shows when 2 recessive genes combine
incomplete dominance 2 traits cross to make an in-between trait; red flower + white flower = pink flower
co-dominance 2 dominant traits shown equally in offspring; black chicken + white chicken = checkered chicken (black and white)
pedigree a genetics family tree; shows how traits move through family generations
genetic engineering technology that involves altering genes and DNA in organisms - different dob greeds
DD homozygous dominant
