|---|---|
| First step of Binary Fission? | 1. Cell elongates and DNA is replicated |

| Reproductive Cell Division Stages? | Gametes -- Fertilization -- Zygote |
| What is Mendel's Law of Segregation? | Each organism contains 2 factors for each trait, and the factors segregate during formation of gametes so that each gamete contains only one factor for each trait. |
| What is an allele and what kinds are there? | It is an alternative form of a gene. Dominant alleles, recessive alleles, gene locus, homozygous (dominant recessive), heterozygous. |
| What is the difference between a genotype and a phenotype? | A genotype is what one's genes say they are where as a phenotype is what one actually looks like. |
| What are the three exchanges of genetic material? | a) synapsis b) crossing over c) Genetic recombination |
| Two different chromosomes | -Autosome -Sex chromosome --Diploid (2n) --Haploid (n) |
| Which chromosome is for a guy and which is for a girl? | Guy- XY Girl- XX |
| You cannot have a population without what key factor? | Genetic Diversity |
| Three possible ways for variation to act on populations.. first? | 1. Gene Mutations |
| Three possible ways for variation to act on populations.. second? | 2. Chromosomal mutations |
| Three possible ways for variation to act on populations.. third? | 3. Recombination |
| Two divisions of genes? | 1. Monomorphic 2. Polymorphic |
| How do you break up the polymorphism genes? | A - 5 Alleles B - 1 Allele C - 2 Alleles D - 1 Allele E - 1 Allele |
| How do you break up Heterozygosity Individuals? | A1 --- A1 A2 --- A3 A1 --- A3 A2 --- A4 A2 --- A2 |
| Genetic Variability is expressed in what three ways.. the first? | 1. The fraction of genes are polymorphic |
| Genetic Variability is expressed in what three ways.. the second? | 2. The average number of alleles for polymorphic genes |
| Genetic Variability is expressed in what three ways.. the third? | 3. The average number of genes that are heterozygous |
| Non-Random Mating includes what? | Inbreeding, assortative mating, sexual selection |
| What are the five important things about the Hardy-Weinbery Principle.. the first? | 1. Large Population |
| What are the five important things about the Hardy-Weinbery Principle.. the second? | 2. No mutation subconsciously |
| What are the five important things about the Hardy-Weinbery Principle.. the third? | 3. No immigrating or emigration |
| What are the five important things about the Hardy-Weinbery Principle.. the fourth? | 4. Random mating |
| What are the five important things about the Hardy-Weinbery Principle.. the fifth? | 5. No natural selection |
| What is the controversy of evolution? | changes views, more than science; disciplines, and battle of worlds |
| Impact Of Theory | Catatrophism --- uniformitarianism Young Earth --- old earth Special creation --- evolution via common descent creator --- strict materialism |
| What are egg and sperm cells produced by and what does that mean? | Meiosis. Therefore, each gamete can only have one gene for each trait. EX: B or b |
| What is a monohybrid? | Plants that are heterozygous for a single trait |
| What is a dihybrid? | Plants that are heterozygous for two traits |
| The first thing you have to realize is that we get two copies of each ____, one from each parent. | gene |
| The second important thing to realize is that the same gene comes in different "flavors," called ____ | alleles |
| First crucial equation when it comes to genetics? | p + q = 1 |
| Second crucial equation when it comes to genetics? | p2 + 2pq + q2 = 1 |
| Proportion of the population that is homozygous dominant (AA) is what? | p2 (pp) |
| Proportion of the population that is heterozygous (Aa) is what? | 2 pq |
| Proportion of the population that is homozygous recessive (aa) is what? | q2 (qq) |
| The inheritance of blood type is controlled by a gene that has three alleles.. the first being? | 1. an allele for the A antigen, designated IA |
| The inheritance of blood type is controlled by a gene that has three alleles.. the second being? | 2. an allele for the B antigen, designated IB |
| The inheritance of blood type is controlled by a gene that has three alleles.. the third being? | 3. an allele for the absence of antigen, i |
| What is a gamete? | when a sperm meets an egg |
| Define Gene flow | The gain or loss of alleles within a population by the movement of individuals or gametes into or out of a population |
| Define Genetic Drift | Change in the gene pool of a population due to chance |
| Proteins in the plasma of the blood are called? | Antibodies |
| Certain proteins present on red blood cells? | Antigens |
| Prokaryote cell division | Mutation Conjugation (exchange of plasmids Transformation Transduction |
| Eukaryotic cell division | stomatic cell division mitosis cytokinesis Reproductive division meiosis cytokinesis |
| Please Make Another Telephone Call | Prophase Metaphase Anaphase Telophase Cytokinesis |
| What are the most obvious features of interphase in plant or animal cells? | Chromatin replicates, nucleus(i) is present & nuclear membrane is present |
| What are the two most obvious difference in plant and animal cell division? | The cell plate & cleavage furrow |
| What is the difference between Mitosis and cytokinesis? | Mitosis divides cells & cytokinesis divides cytoplasm |
| What process is busily occurring in a meristem? | Cytokinesis |
| What is a root cap? | Cells with thin cytoplasm and multiple cell division |
| What is a meristem? | Denser cytoplasm and multiple cell division |
| Major differences between meiosis and mitosis? | Meiosis cuts the chromosomes in half and mitosis is a straight cell division |
| Define spermatogenesis | Formation of reproductive cells called gametes which occurs in testes |
| Define Oogenesis | Formation of ova/eggs which occurs in ovaries |
| What is divergence? | the variations within a taxonomic group |
| What is incomplete dominance or codominance? (Inheritance) | When the resulting phenotype is influenced by two different alleles in the same individual |
| What is dominant-recessive inheritance? | The recessive characteristic will be present only when both alleles are recessive |
