Butler Biology - Meiosis and Electrophoresis Exam Questions and Answers Rated A+
What type of cell begins meiosis? - Answers a diploid germ cell
Centromere - Answers the part of the chromosome that holds the chromatid and the sister chromatid
together
Gamete - Answers sex cells (23 chromosomes)
Autosomes - Answers any chromosome that is not a sex chromosome
Homologues - Answers homologous chromosomes
What happens to the number of chromosomes in the cells created from meiosis? - Answers It goes from
46 chromosomes each to 23 chromosomes each.
How many haploid cells are produced at the end of Meiosis II? - Answers four
Synapsis - Answers the meeting of chromosomes; the process of making a tetrad
Crossing-over - Answers inner chromatids cross over each other's legs and arms; this cuts the genes and
gives them to the other chromatid
a form of genetic recombination
Four Types of Genetic Recombination - Answers -crossing-over
-fertilization
-mutation
-independent assortment
Prophase I - Answers Tetrads are formed through synapsis, crossing-over occurs, and the nuclear
envelope dissolves.
Metaphase I - Answers The tetrads line up in double-file lines.
Anaphase I - Answers The tetrads move to the poles of the cell.
Telophase I - Answers The tetrads split into two haploid daughter cells.
Meiosis II - Answers The two haploid daughter cells from Meiosis I undergo another round of PMAT and
split into four haploid gametes.
Nondisjunction - Answers when chromosomes don't evenly separate in meiosis
Karyotype - Answers a picture of someone's chromosomes
