Overview of Meiosis. 10.1. Overview of Meiosis. Meiosis. - type of nuclear division that reduces the chromosome number from the diploid number to the haploid number.. Gametes. - reproductive cells. Image from about.com . meiosis_metaphase_1.jpg. . Mutations. (changes in an organism’s DNA) are the . original. . source of . all. genetic variation. Mutations create different versions of genes called . ch. : 7. Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources.  . October 29, 2012. The J.

Suppose that the . anole lizard has . fifty-two. chromosomes in the nucleus of its body or somatic cells. How many chromosomes will be in the . unfertilized. . egg. of . an anole lizard. ?. 1. 13. Variations on a Theme. Living organisms are distinguished by their ability to reproduce their own kind. Heredity . is the transmission of traits from one generation to the next. Variation . is demonstrated by the differences in appearance that offspring show from parents and siblings. Review of Mitosis. Mitosis is a form of . asexual reproduction. This means that it . only requires 1 organism . (ex. Skin cells dividing). For growth and repair in . somatic. (body) cells!. Results in 2 cells identical to the original (parent) cell.

Answer the following questions on the back of your review sheet.. 10.2 – Meiosis Sexual Reproduction Function: creates gametes (sperm, egg, pollen) for sexual reproduction .

What is a . G. enetic . D. isease?. Definition: A . genetic disease . is a disease that is inherited from one’s parents and is present from the moment the zygote is created.. Illustrate the steps of meiosis. Describe the roles of crossing over and independent assortment in meiosis . Explain the importance of meiosis to living organisms. Words to know. Crossing over. - the process by which genetic material is exchanged by non-sister chromatids during prophase I of meiosis. Meiosis is the. . type of . cell division by which . germ cells . (eggs and sperm) . are produced. . One parent cell produces . four . daughter cells. . Daughter cells have half the number of chromosomes found in the parent cell. Describe. the advantages and disadvantages of fossil fuels.. Recall. the equation for calculating weight.. Describe. how the reactivity series can be used to select an appropriate extraction method for a metal.
