ECO EVO Study Guide Major Themes: Darwin’s Postulate 1. Heritable variation – (genotype) models of 1-3 loci‚ usually 2 alleles‚ produce heritable phenotypes 2. Organisms engage in a struggle for existence – per capita growth rates from survival and reproduction 3. Heritable traits influence outcome of the struggle – variation affects the struggle; phenotypes (determined by genotypes) influence per capita growth rates 3 Big Questions Biologists seek to answer: 1. Diversity

Using Bloom Taxonomy in the classroom is inviting students to think at higher levels‚ which is a way to encourage students thought processes. Being an approach to make sure an educator can challenge their students beyond the level of mere factual recall. In Bloom Taxonomy the levels increase in degrees of difficulty and students must be able to master the first level before the next can occur. In science you need to start a lesson plan by testing your students’ ability to recall learned factual information

physical separation of alleles during anaphase I of meiosis accounts for Mendel’s principle of segregation. If the alleles for different genes are located on different chromosomes‚ they assort independently from one another in meiosis I. This confirmed the principle of independent assortment. Later on‚ the two scientists came up with the chromosome theory of inheritance‚ which states that independent assortment happens in metaphase and anaphase of meiosis I. To test the theory of inheritance‚ scientist

over. (3 points) The phase in meiosis where chromosomes exchange segments of genetic materials (Campbell‚ 2009). b. Explain why crossing over is important in meiosis. (3 points) Crossing over is the way that genes receive genetic traits from both of the parents. 5. What are the two main differences between mitosis and meiosis? (4 points) a. Crossing over does not occur in mitosis b. The number of cells exchanged is different and mitosis occurs in all organisms and meiosis only occurs in certain organisms

selection in which the condition arises from chromosomal nondisjunction during meiosis in this process‚ the 46 chromosomes in the cell separate‚ ululating producing two new cells having 23 chromosomes each. Before meiosis is completed‚ however‚ chromosomes pair with their corresponding chromosomes and exchange bits of genetic material. In women‚ X-chromosomes pair‚ in men‚ the X and Y-chromosomes separate‚ and meiosis continues. Otherwise it is not something that happens by the law of nature in which

chromosomes. Gametes(sperm and ova) are haploid cells that are produced by meiosis. Diploid cells contain two complete sets (2n) of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Some examples are skin‚ blood‚ muscle cells (also known as somatic cells). 2.

Jamae Gordoncillo Professor Vacura BIO 101 – Lab 31 October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process
