1) In this stage the chromatin condenses making the chromosomes visible. a) Metaphase b) Prophase c) Anaphase d) Telophase 2) During this phase, the highly condensed X shaped chromosomes line up in a single line along the equator of the cell.  a) Metaphase b) Prophase c) Anaphase d) Telophase 3) On each chromosome, the centromere breaks down allowing the sister chromatids to detach and be pulled to opposite poles of the cell. a) Metaphase b) Prophase c) Anaphase d) Telophase 4) Upon reaching the opposite poles, each group of chromatids (now single chromosomes) is surrounded by a newly forming nuclear membrane, and the division of the nucleus is complete. a) Metaphase b) Prophase c) Anaphase d) Telophase 5) These refer to easily observable traits like height or hair color. a) Hereditary b) Acquired c) Morphological d) Physiological 6) They relate to the internal functions of an organism. a) Hereditary b) Acquired c) Morphological d) Physiological 7) They are transmitted from parents to offspring, although they do not always appear in every generation. a) Hereditary b) Acquired c) Morphological d) Physiological 8) They emerge as the result of lifestyle, illness, accidents or environmental influences. a) Hereditary b) Acquired c) Morphological d) Physiological 9) This type of variation can be used to categorize members of a species into different groups. a) Continuous variation b) Metaphase c) Discontinuous variation d) Telophase 10) This type of variation exists when the trait in question has a range of possibilities and an individual can fall anywhere within the range. a) Continuous variation b) Metaphase c) Discontinuous variation d) Telophase 11) The characteristics that allow us to distinguish individuals from one to another are called ... a) genome b) traits c) karyotype d) genes 12) The analysis of the number and shape of chromosomes present in an individual organism is called the ... a) karyotype b) traits c) genes d) genome 13) ... is the division of the cell's nucleus. a) karyotype b) traits c) meiosis d) mitosis 14) ... , a second type of cell division is used to produce gametes.  a) karyotype b) traits c) meiosis d) mitosis 15) Produces two identical, diploid daughter cells while meiosis produces four distinct, haploid gametes. a) karyotype b) traits c) meiosis d) mitosis 16) During telophase, shortly before mitosis is completed, the cytoplasm begins to divide in the process known as ... a) karyotype b) cytokinesis c) meiosis d) mitosis 17) Together, all of the genes in the cell or in an organism are known as the ... a) chromosomes b) genes c) genomes d) traits e) cleavage 18) During cell division, the chromatin condenses into special structures called ... a) chromosomes b) genes c) genomes d) traits e) cleavage f) cells 19) In animal cells, a contractile ring gradually reduces the diameter of the cell around its equator.
