Chi Squared!!! * If the Χ 2 is smaller than the critical value for the indicated degrees of freedom, then we FAIL TO REJECT the null hypothesis. *If the Χ 2 is larger than the critical value for the indicated degrees of freedom (# classes-1),then we • REJECT the null hypothesis and something is going on to cause this.
Equation for Photosynthesis • _______+______ _______+_________

What theory could explain why both chloroplasts and mitochondria have two membranes?
If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous(Ss) for the sickle-cell gene? • This is a classic data set on wing coloration in the scarlet tiger moth (Panaxiadominula). Coloration in this species had been previously shown to behave as a single-locus, two-allele system with incomplete dominance. Data for 1612 individuals are given below: • White-spotted (AA) =1469 Intermediate (Aa) = 138 Little spotting (aa) =5 • Calculate the following frequencies: (f)A = (f)a = (f)AA = (f)Aa= (f)aa=
For in-state @ Clemson roughly 800$ per credit hour (give or take) This means for non-bio majors= $6,400!!! For Bio majors= $8,000!!!
Which is Metaphase of Mitosis and which is Metaphase I of Meiosis?
Punnett Square • The Punnett square is a useful diagram for determining gene combinations.
Punnett Square • Organisms that have two identical alleles for a trait are called homozygous.(TT or tt) Purebred • Organisms that have two different alleles for the same trait are called heterozygous (Tt) Hybrid • Phenotype is the physical characteristic of a trait (Tall or short) • Genotype is the genetic makeup (TT, Tt, or tt)
Dihybrid Cross • This is a cross between two individuals for two different traits. Typically resulting in a 9:3:3:1 ratio of traits. http://science.nhmccd.edu/biol/dihybrid/dihybrid.html
Testcross (cross with homo. Recessive) to determine unknown parent genotype
Gene Linkage • Recombinants (lowest numbers of offspring) divided by total offspring • Multiply by 100 to get map distance
Other Genetic Aspects • Not everything is as easy as Dominant and recessive. • Incomplete dominance: cases in which one allele is NOT completely dominant over another allele. • Codominance: cases where both alleles contribute to the phenotype of the organism. • Multiple alleles: genes that have more than two alleles. • Polygenic traits: traits controlled by two or more genes.
Replication Process • Step 1: ________, a special enzyme, unzips a strand of DNA by breaking H-bonds between the N-bases. • Step 2: a primer is placed onto each strand by ___________to give the building enzymes a starting point. • Step 3: the building enzyme called _____________ fills in the two strands with free nucleotides. • Step 4: after some modification by DNA polymerase and other enzymes, a final enzyme called _________‘glues’ the strands together. http://www.wiley.com/college/pratt/0471393878/student/animations/dna _replication/index.html http://207.207.4.198/pub/flash/24/menu.swf
Central Dogma in Biology • Process? Where? • Process? Where? • Process? Where?
Quick Practice • DNA strand • TACGGCAAG ATT • mRNA (codons)? • Protein (amino acids)? ***Anticodons of tRNA would just be the complementary RNA N-bases to the mRNA codons.***
