Chapter 10, Problem 5TYU
DRAW ITThe diagram shows a cell in meiosis. (a) Label the appropriate structures with these terms: chromosome (label as duplicated or unduplicated), centromere, kinetochore, sister chromatids, nonsister chromatids, homologous pair (use a bracket when labeling), homolog (label each one), chiasma, sister chromatid cohesion, gene loci, alleles of the F gene, alleles of the H gene. (b) Identify the stage of meiosis shown. (c) Describe the makeup of a haploid set and a diploid set.

An organism with two of each kind of chromosome is said to be:
(3) tetraploid
(1) haploid
(2) diploid
(4) polyploid.
In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair
(3) sperm and egg production (4) fertilization.
If an organism produced an egg that had 20 chromosomes, the body cells of that organism
should have: (1) 10 chromosomes (2) 20 chromosomes (3) 30 chromosomes

Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.
