Co-dominance correct answer: Situation in which both alleles of a gene contribute to the phenotype of the organism due to their mutual dominance. There are in total 2 alleles, two being dominant and 1 recessive. Genotype correct answer: An organism's genetic makeup, or allele makeup. Blood type correct answer: Determined by the type of antigen present on the surface of red blood cells O Blood Type correct answer: universal donor AB blood type correct answer: Donates to A, can t...

binary fission - asexual, usually in prokaryotes origin (of replication) - bidirectional (replication AND separation together) homologous chromosome (homologue) - one from mom, one from dad; similar not identical; same alleles in the same order chromatid; sister chromatid - two IDENTICAL halves of a single replicated eukaryotic chromosome histone - proteins that have DNA wrapped around them in the *nucleosome* structure nucleosome - 147nt of DNA wrapped around a core of 8 histone proteins ...

Electron Transport Chain (ETC) Four protein complexes in the inner mitochondrial membrane form the electron transport chain. -Here the electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages. - NADH + H+ and FADH2 become oxidized, donating electrons to the first and second protein complex respectively. The independent variable in an experiment is the one thing that is varied between experimental grou...

The independent variable in an experiment is the one thing that is varied between experimental groups. The effect of the independent variable is typically what is being analyzed. In the situation described, the independent variable is the method by which the passage is presented to the test subjects, either aurally or visually. continuous variation Human skin color, height, and weight are influenced by many genes as well as environmental factors. When the frequency in a population of differen...
