You are studying a cell which, before the S phase of the cell cycle, has 8 chromosomes and 1.2 picograms (1.2 × 1012 grams) of DNA. Complete the following table with the expected number of chromosomes, chromatids, and homologous pairs, and the amount of DNA in each area or pole of the spindle at each of the stages indicated. Chromosomes Chromatids Homologous pairs DNA amount Prophase (Mitosis) Anaphase (Mitosis) Prophase I (Meiosis) Anaphase I (Meiosis) Anaphase II (Meiosis) 1. A female Drosophila (fruit fly) heterozygous for red eyes and grey body was crossed with a male homozygous for scarlet eyes and ebony body. The two genes are linked on the same chromosome. The following offspring were produced. How many map units would separate them? Red eyes, grey body 76 Red eyes, ebony body 26 Scarlet eyes, grey body 30 Scarlet eyes, ebony body 68 5. In a certain breed of domestic fowl, super comb is dominant to single comb but feather colour shows absence of dominance. Black legs and white legs are homozygous, whereas the heterozygote gives red legs. From crosses between birds heterozygous for both genes, what proportion of the offspring would you expect to be: (Define the alleles and show work using a Punnett Square.) 1. Super-combed2. Black-legged3. Red-legged4. Super-combed and red-legged 5. Single-combed and white-legged 5. List 4 features of an ideal organism for the study of genetics.

Question What does it refer with Evaluation of the resources? The Research Project/Presentation for this class is divided into three major Assignments, 1) annotated bibliography, 2) outline and 3) final presentation. The first part is the annotated bibliography. An annotation is a summary and evaluation, and your annotated bibliography will include a summary and evaluation of some of the sources (or references) you will use for your presentation.

Question One concern that has been raised concerning the production of biofuels (ethanol or biodiesel) is the use of land that could be used for raising food for humans. Cities are also expanding into farming areas reducing the available crop land. Discuss how you believe biofuels could be produced without competing for space with food crops. Consider type of soil, amount of sunlight, etc.

Arsenic life debate part 2. Using agarose pieces to calculate
Question Arsenic life debate part 2. Using agarose pieces to calculate the arsenic to to carbon ration is a mistake, because agarose contains many atoms of carbon, and therefore the arsenic to carbon ratio will depend on factors such as the size of the agarose chuncj used in the experiment. What do you propose as proper control for this experiment?
