Biology Study Guide/Test Review CH 11-4 Meiosis
Be sure you know the definitions of Haploid & Diploid.
You will have to APPLY haploid (N) & diploid (2N) information.
Mitosis results in ________ (how many) cells, whereas MEIOSIS results in ________ (how many) cells.
The # of chromosomes in a gamete is represented by the symbol ___________. The # of chromsomes in a
body cell is represented by the symbol __________.
Define gamete.
Define allele.
Gametes have _______________ allele for each gene.
Define CROSSING OVER and be sure you understand the diagram of crossing over!
Unlike mitosis, meiosis results in the formation of __________________ genetically _____________ cells.
Gametes are produced by the process of ___________________.
An organisms gametes have ________________ the # of chromosomes found in the organism’s body cells.
What might happen if the gametes of a species had the same # of chromosomes as the species body cells?
(this is an application question!)
Crossing over occurs during what SPECIFIC stage of meiosis?
Define homologous chromosomes.
What happens to the number of chromosomes per cell during meiosis?
EXPLAIN why daughter cells produced by meiosis are genetically different from each other, whereas the
daughter cells produced by mitosis are not.
UNDERSTAND & BE ABLE to EXPLAIN the diagram of meiosis. Be able to tell the difference in the
formation of sperm cells as compared to the formation of egg cells. PLEASE be sure you know the # of
cells produced, size comparison, plus the genetic similarities and differences in the cells produced by
Meiosis!
