5 Matching Questions
- a the different forms of a gene
- b each chromosomes that came from the male parent has a corresponding chromosome from the female parent
- c sex cells
- d the process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
- e fertilized egg
5 Multiple Choice Questions
- "two sets" a cell that contains both sets of homologous chromosomes (2N)
- chromosomes become visible. chromosomes do not pair to form tetrads because homologous pairs were already separated during meiosis 1.
- chromatids of the homologous chromosomes cross over one another and alleles are exchanged.
- chromosomes line up at the center of each cell
- "one set" a cell that contains a single set of chromosomes. (N)
5 True/False Questions
anaphase 1 → spindle fibers pull each homologous chromosome pair toward opposite ends of the cell.
metaphase 1 → chromosomes line up at the center of each cell
telephase 2 and cytokinesis → each of the four daughter cells produced in meiosis 2 receive two chromatids
prophase 1 → each replicated chromosome pairs with its corresponding homologous chromosome.
Mitosis v. Meiosis → Mitosis is asexual reproductiona and meiosis is sexual reproduction. in mitosis daughter cells get one set of chromosomes. In meiosis homologous chromosomes move to separate daughter cells. meiosis reduces chromosome number by half.
