Alright, here's a simpler version. I drew up a picture for you, which is attached to this post. 

Similarities by phase

Prophase: Both involve condensing the chromatin and getting rid of the nuclear envelope (not drawn). Here, we have two sets of example homologous chromosomes, where blue/red are a pair and green/purple are a pair.

Metaphase: Both involve lining up the chromosomes along the cell's midline.

Anaphase: Both involve pulling pairs of something apart (what type of pairs is different, see below).

Telophase: Both involve cleavage of the cells, cytokinesis, and the nuclear membrane reforming.

Daughter cells: Both produce 2 daughter cells per cell starting the process.

Differences by phase

Prophase I: Here, chromatin condenses into tetrads, which are two sets of sister chromatids (red/blue and green/purple) of homologous chromosomes (the chromosomes that pair up with each other in the diploid organism).

Prophase II: Chromatin simply condenses into sister chromatids. No homologous pairs are present because they have already been pulled apart.

Metaphase I / II: Not much of a difference here.

Anaphase I: The chromatin being pulled apart are the homologous chromosomes (blue and red separate, green and purple separate). Sister chromatids stay together (the the colored pairs are still paired in the final daughter cells).

Anaphase II: Sister chromatids are pulled apart in this phase.

Telophase I/II: Not much of a difference here, either.

Daughter cells from I: These daughter cells are haploid because there are no longer homologous pairs, but they have duplicates of the chromosomes that they contain (2 blues and 2 greens vs. 2 reds and 2 purples).

Daughter cells from II: These daughter cells are haploid, too, but they do not contain duplicate material (1 blue and 1 green, 1 blue and 1 green, 1 red and 1 purple, 1 red and 1 purple).

I left out some of the details, like crossing over (Prophase I), things that allow the differences to happen, and differences between sexes, but I hope this works for you, considering how much trouble you seem to be having in getting the answer you're looking for!
