In Coleus , the somatic cells are diploid with 24 chromosomes. How many of each of the following is present in each cell at the stage of mitosis and meiosis indicated below? kinetochore at prophase   chromosomes at anaphase   chromatids at metaphase 1   chromosomes at telophase after cytokinesis   centromeres at anaphase       chromosomes at telophase II after cytokinesis        centromere at anaphase I   chromatids at metaphase

Truffles (Tuber borchi) have 2n=8 chromosomes. For the mitotic and meiotic stages below, draw the chromosomes and chromatids, and give the number of homologous pairs, chromosomes, and chromatids present. Be sure to differentiate homologous chromosomes by using size, shape, or other labeling mechanism. Metaphase of mitosis ( # homologous pairs # chromosomes # chromatids Anaphase of meiosis II – draw and count chromosomes for only 1 cell ( # homologous pairs # chromosomes # chromatids

Which of the following events takes place in meiosis but not in mitosis? Breakdown of the nuclear envelop Condensation of chromosomes Separation of homologous chromosomes Separation of chromatids Cytokinesis

Which of the following statements are true regarding mitosis in humans? (Check all that apply)   46 pairs of sister chromatids are separated 46 pairs of homologous chromosomes are separated 23 pairs of sister chromatids are separated 23 pairs of homologous chromosomes are separated two genetically identical daughter cells are produced four haploid gametes are produced in males 1 haploid gamete and 2 polar bodies are produced in females

Which of the following events does not normally occur in mitosis?     Separation of sister chromatids from each other     Formation of synaptonemal complexes     Attachment of spindle fibers to centromeres     Movement of sister chromatids to opposite poles     Alignment of chromosomes along the metaphase plate

Describe the key event involving chromosomes that take place during the followingportions of the cell cycle in mitosis and sketch a diagram.

If a parent cell of a sexually-reproducing species has 28 chromosomes, the number of chromosomes in the zygote would be 14.    28.    56.    112.    impossible to determine with the information given.   A tetrad is composed of       two chromosomes with two sister chromatids each.       two sister chromatids with separate centromeres.     four chromosomes with two sister chromatids each.     four sister chromatids are attached at a common centromere.      QUESTION 3 During crossing-over     genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.     genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles.     sister chromatids from each homologous chromosomes of a tetrad are exchanged, resulting in new combination of alleles.     one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations…
