1 .Asexual reproduction _____. (Concept 13.1) is restricted to plants leads to a ns of hereditary material to produce offspring genetically identical to the parent needs both meiosis and mitosis is minimal to single-cell organisms 2 .A human somatic cell has _____. (Concept 13.1) 22 autosomes and 1 sex chromosome 21 autosomes and also 2 sex chromosomes 45 autosomes and also 1 sex chromosome 44 autosomes and also 2 sex chromosomes n chromosomes 3 .For what purpose might a karyotype be prepared? (Concept 13.2) because that prenatal screening, to determine if a fetus has the correct variety of chromosomes to determine whether a fetus is male or female come detect the possible presence that chromosomal abnormalities such together deletions, inversions, or translocations The an initial and 2nd answers space correct. The an initial three answers space correct. 4 .The diploid phase of a tree that complies with the life cycle dubbed alternation of generations is the _____. (Concept 13.2) chiasmata gametophyte spore karyotype sporophyte 5 .One difference in between meiosis I and meiosis II is that _____. (Concept 13.3) just meiosis I consists of prophase, metaphase, anaphase, and also telophase crossing over occurs in meiosis I, however not in meiosis II the 2 daughter cells produced at the finish of meiosis i are various from each other, yet the 2 cells produced in meiosis II are identical only meiosis ns occurs in males, however both meiosis I and meiosis II take place in females chromosomes line up in ~ the metaphase plate during meiosis I, but remain dispersed throughout the cell during meiosis II 6 .Mitosis results in the formation of _____; meiosis results in the development of _____. (Concept 13.3) 4 diploid cell ... 4 haploid cells two diploid cell ... Two haploid cells two diploid cells ... Four haploid cells 2 diploid cell ... 2 diploid cells four haploid cells ... Two diploid cell 7 .Which of the following occurs during meiosis yet not throughout mitosis? (Concept 13.3) Chromosomes align at the metaphase plate. Chromosomes condense. Chromosomes migrate to opposite poles. A spindle apparatus forms. Synapsis occurs. 8 .Crossing over is _____. (Concept 13.3) the motion of genetic material native one chromosome come a nonhomologous chromosome also referred to as the \"independent assortment of chromosomes\" a direct repercussion of the separation of sister chromatids the exchange that homologous sections of nonsister chromatids do an RNA copy that a DNA strand 9 .Genetic sports occurs when chromosomes space shuffled in _____ and fertilization.

You are watching: Variation occurs when chromosomes are shuffled in _____.
