The difference between prophase I and II is that in prophase I
Multiple Choice
A ) the nuclear membrane disappears.
B ) chromosomes coil.
C) the nucleolus disappears.
d) the spindle forms.
e) synapsis and crossing over occur.
Homework Answers
Answer:
e) synapsis and crossing over occur.
Answer:
The synapsis and crossing over occur are the events occur in prophase I of meiosis I only but not in meiosis II. Meiosis II is similar to mitosis, where there is not synapsis and crossing over.

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...
