Question
Chapter 28, Problem 2IQ
Summary Introduction
To determine: Whether the Ulva gametes are formed by meiosis.
Introduction: Mitosis results in the doubling of the haploid genetic content in the cell causing the production of a diploid zygote. The process of meiosis results in no change in the haploid content as the process produces gametes that consist of only one set of chromosomes in the cell. The mitosis takes place in somatic cells and meiosis in gametic cells.

What allows sister chromatids to finally separate, and in
which phase of meiosis does this occur?
a) release of cohesin along sister chromatid arms in anaphase I
b) crossing over of chromatids in prophase I
c) release of ohesin at centromeres in anaphase I
d) release of cohesin at centromeres in anaphase II
e) crossing over of homologs in prophase I

Please answer remaining 4
Match the phases of meiosis with their descriptions.
Question 6 options:
chromatids of chromosomes are pulled apart and move toward the cell sides
nuclear membrane disappears and tetrads form
chromosomes align along the middle of the cell
tetrads align along the middle of the cell
chromosomes from tetrads reach the sides of the cells and the nulcear membrane reforms
chromatids of chromosomes reach the cell sides and the nuclear membrane reforms; cytokinesis occurs near the end
chromosomes reside in the cell's center and the nuclear membrane disappears
chromosomes of tetrads separate and move toward the cell sides
