    nucleotides to DNA.

    *64 different codons, but only 20 amino acids.

    TRANSLATION

Protein Synthesis (continued)

AAAARGH!!!

MUTATIONS- Random alterations in DNA

  • Point Mutation – a single base is changed to another

    AUG AAA UAG

    AUG AAG UAG Neutral mutation (AAA & AAG are both lysine)

  • Frameshift– a deletion or addition of a base that may significantly change the function of a protein. This changes every codon after the deletion or insertion.

    AUG AAA UAG

    AUG AAU AG

Have you seen this pirate?

Mendelian genetics continued

MendelianGenetics (continued)

  • Practice the FOIL method to determine the possible gamete combinations for the following parental genotypes.

    -RrYy= _____ -FFBb= ______ -ttGG=______

  • Work out the genotype ratio for the cross between 2 parents who are RrYy & RrYY.


Non mendelian genetics

Non-mendelian Genetics

  • Incomplete Dominance: There is no dominant or recessive, the heterozygous condition results in a "blending" of the two traits.

  • Codominance: Both alleles in the heterozygote express themselves fully.

  • Multiple Alleles: A gene that has more than two possible alleles, though only two alleles are present at a time. Ex. Blood types

    Solve the Punnett Squares:

  • Black and White alleles are co-dominant and create speckled offspring. What would be the phenotype ratio of the cross between two speckled chickens? B= Black, W = White, BW = Speckled
