  1. WILD TRAITS
    SYMBOLIZED USING THE INITAL LETTER OR COMBINATION OF TWO OR 3 LETTERS WITH A +

    • DOMINATE TRAITS CAPITALIZED
    • RECESSIVE TRAI LOWER CASE

    MUTANTS TRAIS ARE SYMBOLIZED USINT THE SAME LETTERS WITHOUT A +
  2. INCOMPLETE DOMINANCE
    • NEITHER ALLELE DOMINTATES
    • THE HETEROZYGOUS INDICIDUAL HAVE AN APPEARANCE IN BETWEEN THE PHENOTYPES OF THE HOMOZYGOTES
  3. CODOMINANCE
    HETEROZYGOTE HAS JOINT OR EQUAL EXPRESSSION OF BOTH ALLELES
  4. MULTIPLE ALLELE INHERITANCE
    HAPPENS WHEN 3 OR MORE ALLELES EXIST FOR ONE GENE
  5. 2 TYPES OF MULTIPLE GENE INHERITANCE
    POLYGENIC INHERITANCE

    EPISTASIS
  6. POLYGENIC INHERITANCE
    ADDITIVE EFFECTS OF 2 OR MORE GENS ON SINGLE PHENOTYPE

    SEVERAL GENS REGULATE SKIN COLOR
  7. EPISTASIS
    OCCURS WHEN THE ALLES OF ONE GENE COVER UP OR ALTER THE EXPRESSION OF ALLELES OF ANOTHER GENE
  8. SEX CHROMOSOMES
    CARY MORE GENES THAN THOSE INVOLVED IN SEX DETERMINATION

    DISTICT PATTERN OF INHERITANCE CALLED X LINKED OR SEX LINKED INHERITANCE
  9. X LINKED
    GENES DETERMINING THE PHENOTYPE ARE CARRIED ON THE X CHROMOSOMES AS THE RESULT THE SEX EXPERIENCE VARYING PATTERN OF INHERITANCE
  10. X LINKED
    HEMOPHILI IN HUMANS IS LINKED TO THE X CHROMOSOME

    FEMALES HAVE 2 X CHROMOROMES AS RESULTS THEY HAVE A BACK UP
  11. SEX LIMITED
    TRAITS THAT ARE EXPRESSED IN ONLY ONE SEX EVEN THO ITS NOT CARRIED ON THE SEX CHROMOSOMES
  12. SEX INFLUENCED
    PHENOTYPIC EXPRESSION IS CONDITIONED BY SEX OF THE INDIVIDUAL

    HETEROZYGOTE MAY EXPRESS ONE PHENOTYPE IN ONE SEX AND THE ALTERNATE PHENOTYPE IN THE OPPOSITE SEX
  13. PLEIOTROPY
    IMPPACT OF A SINGLE GENE ON MORE THAN ONE CHARACTERISTIC

    ONE ALLELE THAT IS EXPRESSED IN VARIOUS PHENOTYPIC FORMS
  14. SICKLE CELL DISEASE
    CHARACTERIZED BY A DIVERSITY OF SYMPTOMS
  15. CYTOPLASMIC INHERITANCE
    MITOCHONDRIA POSSESS A SMALL AMOUT OF DNA

    600,000GENS IN THE NUCLEUS AND 37 GEIN IN MITOCHONDRIA

    • 13 PROTEINS FOR CELLULAR RESPIRATION
    • 22 TRANSFER RNA (TRNA) FOR TRANSLATION
    • 2 RIBOSOMAL RNAS (RRNA) FOR TRANSLATION
  16. CYTOPLASMIC INHERITANCE
    MITOCHONDRIA DNA PASSED ON BY MOTHER ONLY

    • MITOCHONDRIA IN SPERM DO NOT TAKE PART IN GAMETE UNION
    • AS EMBRYO DIVIDES SO DOES THE MITOCHONDRIA
  17. MITOCHONDRIAL DEFECTS
    ARE INHERITEED THROUGH THE MATERNAL LINE
  18. GENETIC DISEASES RESULT FROM HETEROPLASMY
    • MYOCLONIC EPILEPSY/RAGGED RED FIBER DISEASE (LACK OF MUSCLE COORDINATION, DEAFNESS,DEMENTIA, EPILEPTIC SEIZURES)
    • LEBERS OPTIC NEUROPATHY( BILATERAL BLINDNESS)
    • KEARNS(BLINDNESS DEAFNESS AND HEART CONDITIONS)
  19. LINKED GENES
    GENS LOCARED CLOSE TO EACH OTHER ON THE SAME CHROMOSOME

    TYPICALLY INHERITED TOGETHER

    DURING CROSSING OVER GENES CLOSE TO ONE ANOTHER DO NOT GET SEPERATED
  20. CROSSING OVER
    THE FATHER APART ON THE SAME CHROMO GENE ARE MORE LIKELY THEY WILL SEPARATE DURING RECOMBINATION
  21. EXTREMES OF CROSSING OVER
    INDEPENDENT ASSORTMENT & COMPLETE

    ABSOLUTE LINKAGE
  22. RECOMBINANT FREQUENCY
    GREATER RECOMBINATION FREQUENCIES ARE OBSERVED FOR GENES THAT ARE FARTHER APART ON THE CHROMOSOMES
  23. GENETIC SUPPRESION
    SUPPRESSOR GENE CAUSES THE COMPLETE REVERSAL OF THE EXPECTED PHENOTYPE
  24. POSITIONAL EFFECT
    PHYSICAL LOCATION OF A GENE IN A GENOME MAY EFFECTITS EXPRESSION
  25. TEMPERATURE SENSITIVE
    MUTATIONS ARE TEMPERATURE SENSITIVE
  26. NUTRITIONAL MUTATIONS
    LACK OF NUTRIENT VITAMINS MINERALS OR ORGANICE MOLECURE PREVENT THE COMPLETE EXPRESSION OF THE GENE

    SOME DISEASE IN HUMANS CAN BE DUE TO A NUTRIENT THAT GENES ARE INCAPABLE OF PROCESSING
  27. GENOMIC IMPRINTING
    • DURING MEIOSIS SOME GENS ARE IMPRINTED
    • METHYL GROUPS ADDE ON CYTOSINES
    • CAUSE GENE TO INACTIVATE OR ACTIVATED

    PHENOTYPE IN OFFSRPING DEPEND ON ALLELE FROM MOTHER OR FATHER
