  • Week 24  Ch. 12.2-3 pg 315When HeredityFollows DifferentRules
  • Click here for acomplete Gene E in a bottle incompletedominance dominancethe offspring will show only the When the offsping show traits intermediate betweendominant trait in its phenotype dominant and recessive,ex Black (BB) X White (bb) = ex Black (BB) X White (bb) =White (Bb) Gray (Bb) phenotype genotype 100% heterozygous
  • alleleOne form of a gene,Ex. there are three different ______s for blood – A, B, and O
  • codominant allele Allele that is expressed equally with another dominant allele, co-starring Ex. White (WW) X Black (BB) = Black and White Spotted(BW) WW BB W BW BW All BW BW heterozygous W
  • multiple allele trait See video Trait controlled by more than two alleles Example: Humans have three alleles for blood - A(IA), B(IB), and (IO)
  • autosomeNon-sexchromosomes This is a human karyotype
  • sex chromosomeChromosomes that determine the sex of an individual, X and Y Male xy Female xx
  • sex-linked traitTraits controlled by genes on sex chromosomesex. Female carrier for Hemophilia (X X ), H h Hemophiliac male (XHY)Hemophiliac female (XHXH) Color blindness – X-linked Male pattern balding 4 Sex-Linked Traits: 2. Normal Color Vision: A: 29, B: 45, C: , D: 26 hemophilia 3. 2. Red-Green Color-Blind: A: 70, B: , C: 5, D: 4. 3. Red Color-blind: A: 70, B: -, C: 5, D: 6 5. 4. Green Color-Blind: Hairy ears A: 70, B: , C: 5, D: 2 Female pattern balding
  • polygenic inheritanceInheritance pattern of a trait that is controlled by two or more genesex. height, skin color, eye color
  • external internalenvironment environment Survival based on Temperature, gender, age, nutrition, light, interaction with chemicals, other organisms infectious agents
  • sickle celldiseaseCauses defective hemoglobin which changes shape of blood cell into a sickle, or half- moon, blocking blood flow
  • Name 4 Human blood typeswith their genotypes Blood type animation Phenotype Genotype Type A IAi or IAIA Type B IBi or IBIB Type AB IAIB Type O ii
  • red-green color blindnessCaused by recessive genes on X chromosome, affects green and red receptors in eyes
  • hemophiliaX-linked disorder that causes problem with the bloods ability to clot
  • A polygenic trait, indicatedskin color by three or four genes
  • karyotypeA chart showing chromosome pairs Catfish
  • Down Syndrome Results from trisomy of chromosome 21, tri = 3
  • Protein Synthesis  Transcription  Translation
  • Here are some true/falsequestions for you
  • What determines structure and function of cells? The DNA molecule
  • Offspring receive geneticinformation (DNA) from their parents.
  • Chromosomal mutations may lead to genetic variation
  • Some mutations are good, andhelp an organism survive.True or False? True, but not often
  • Plants reproduce sexually andasexually. True or false? True
  • DNA in one organism (like a mouse) hasmany similarities with DNA in anotherorganism (like you). True or False? True Mouse Human
  • Every cell within an organismhas same DNA. True or False? True Liver cell Brain cell
