Homologous chromosomes pair and undergo crossing over during?
Paired homologous chromosomes are found at the spindle equator during metaphase. During metaphase the chromosomes line up on the plate and attach to the fully formed spindle.
What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
During Metaphase 1 the homologous pairs of chromosomes line up at the center of the cell. They arrange around the spindle during meiosis.
What is spindle fibers pull the sister chromatids apart?
During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes.

Which event occurs during metaphase?
chromosomes migrate to equator of the spindle apparatus
What is propahse?
It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.

Which phase pulls spindle fibers apart from homologous chromosomes?
Anaphase

What phase in Meiosis do spindle fibers move homologous chromosomes to opposite sides?
Anaphase 1
Which event occurs during metaphase?
chromosomes migrate to equator of the spindle apparatus
What attaches chromosomes together?
SPINDLE FIBERS!!
What joins chromosomes arms together and is the place where spindle fibers attach to each chromosome?
centromere joins chromosomes arms , the cromatids , together and is the place where spindle fibers attach to each chromosomes
What is the Disjunction of homologous chromosomes to the opposite poles?
During anaphase, the centrosomes (which have moved to opposite poles of the cell) release microtubules from their centrioles which then pull the chromosomes towards them, the double stranded chromosomes then split at the centromere and thus each pole of the chromosome has a copy of every chromosome. I assume you're talking about meiotic division though and in this case the spindle fibres/ microtubules dont split the chromosomes in half, rather, the chromosomes line up in homologous pairs (instead of in single file) and the spindle fibres pull one of the entire homologous double stranded chromosomes to its designated pole.

What holds chromosomes together?
The centromere holds chromosomes together. It is the circle like thing in the middle of the chromosome.
7th grade The eight steps of meiosis?
Prophase I: chromosomes start to condense and become visibleMetaphase I: homologous chromosomes line up at equatorial plateAnaphase I: homologous chromosomes separate and move to diferent polesTelophase I: one set of chromosomes arrive at each poleProphase II: chromosomes condense againMetaphase II: individual chromosome line up at equatorial plateAnaphase II: centromere divides, and chromosomes (from chromatids) move to different polesTelophase II: one set of chromosome arrive at each pole.
