1. Draw out ALL of the stages of Mitosis AND Meiosis (I and II). Use at least 3 homologous pairs.
2. Label each stage and the hallmark of that stage. Show how chromosomes align and segregate
3. Show the points (indicate in drawing where possible) where genetic diversity is introduced AND how it contributes to diversity (Assortment of chromosomes, Random fertilization, Crossing-over between non-sister chromatids)
How does trisomy 21 occur? During which stages? Indicate on your drawing for #1

What is a major difference between mitosis and meiosis I in a diploid organism? Only meiosis I results in daughter cells that contain identical genetic information. Sister chromatids separate in mitosis; homologous pairs of chromosomes separate in meiosis I. Sister chromatids separate in mitosis; homologous pairs of chromosomes separate in meiosis II. ODNA replication takes place prior to mitosis, but not before meiosis I.
2. Which of the following occurs during mitosis but not during meiosis I?
2. Which of the following occurs during mitosis but not during meiosis I? a. The chromosomes are pulled to opposite poles of the spindle apparatus. b. The chromatids of each chromosome are separated. c. The nuclear envelope breaks down. d. Both synapsis and crossing over take place. e. The diploid number of chromosomes is reduced to the haploid number.3. Table 1 shows the stage and number of cells and chromosomes per cell at the end of the stage in a 2n - 24 organism. u...

all these questions have more than one correct answers 1) Meiosis & mitosis have similarities as well as differences. Which of the following represent similarities? a) Both increases genetic variation b) Both change in chromosomes number in daughter cells c) Both only occur in eukaryotes D) DNA replication must occur prior to both e) Both make use of a spindle to separate chromatids 2) Meiosis is a special form of cell division.

Mitosis and Meiosis. 1. Draw a cell where 2n = 6 in each phase of Mitosis, Meiosis 1, and Meiosis 2. Be sure to clearly indicate what is going on with the 1-nuclear envelope, 2-centrosomes, 3-chromosomes in each of the stages. 2. For a diploid organism where 2n = 16, please indicate the number of chromosomes and chromatids at each of the Mitosis, Meiosis 1, Meiosis 2 stages.

Crossing over is one of the most important events in meiosis because __. A) homologous chromosomes are separated into different daughter cells B) the number of chromosomes allotted to each daughter cell must be halved C)sister chromatids must be separated into different daughter cells D) it produces new arrays of alleles on chromosomes and contributes to genetic diversity
