chart of chromosome pairs
karyotype
inheritance pattern of a trait that is controlled by two or more genes
polygenic inheritance
sex-linked trait
traits controlled by genes located on sex chromsomes
the two chromosomes which determine the sex of an individual
sex chromosome
22 pairs of matching homologous chromosomes
autosomes
traits controlled by more than two alleles
multiple alleles
cause the phenotypes of both homozygotes to be produced in heterozygoous individuals
codominant alleles
phenotype of the heterozygote is intermediate between those of the two homozygotes
incomplete dominance
developing baby
fetus
heterozygous individual
carrier
graphic representation of genetic inheritance
pedigree
average of dominant and recessive
incomplete dominance
dont average/both dominant and recessive alleles are expressed equally
codominant alleles
most common lethal genetic disorder among white American, very thick mucus/defective protein in plasma membrane
cystic fibrosis
recessive allele results in the absence of an enzyme that normally breaks down a lipid , CNS disorder
tay-sachs
PKU doesnt make enzyme to break down phenlyalanine to tyrosoine
PKU phenylketonuria
lethal breakdown of certain areas of the brain, symptoms occur around 30-50, dominant autosomal
huntingdons
discovered traits
thomas hunt
traits controlled by genes located on sex chromosomes
sex-linked traits
traits controlled by more than two alleles
multiple alleles
inheritance pattern of a trait that is controlled by two or more genes
polygenic inheritance

proteins on the outside of your red blood cells
antigens
red/green color blindness
sex-linked traits
cant clot blood/ carried on X chromosomes/queen victoria
hemophilia
dont migrate right
nondisjunction
aneuploidy
abnormal # of chromosomes
produces organisms with desired traits
selective breeding
mating between closely related individuals
inbreeding
offspring of selective breeding
hybrid
cross of an individual of unknown genotype with an individual of known genotype
testcross
faster/reliable method for increasing the frequency of an allele
genetic engineering
connecting fragments of DNA
recombinant
find foreign DNA to be used
1
attach the DNA to a vector that'll introduce DNA segment to the host
2
transfer dna vehicle into the host organism
3
breakdown of all pollutants
industry
human disease treatment/transgenic animals to study disease
medicine
bigger/better more disease resistant/human genome project
