Meiosis

synaptonemal complex

The ________, a lattice of proteins between the homologous chromosomes, forms at specific locations and then spreads to cover the entire length of the chromosomes.

random assortment

The cells produced are genetically unique because of the ________ of paternal and maternal homologs and because of the recombining of maternal and paternal segments of chromosomes that occurs during crossover.

nuclear envelopes

In some organisms, the chromosomes decondense and ________ form around the chromatids in telophase I.

sister chromatids

During the anaphase I, the microtubules pull the linked chromosomes apart and the ________ remain tightly bound together at the centromere.

genes

In synapsis, the ________ on the chromatids of the homologous chromosomes are aligned precisely with each other.

Kinetochore proteins

________ are multiprotein complexes that bind the centromeres of a chromosome to the microtubules of the mitotic spindle.

II

During telophase ________, the chromosomes arrive at opposite poles and begin to decondense.

telophase

During ________ I, the separated chromosomes arrive at opposite poles and the rest of the ________ process may or may not occur, depending on the species.

homologous chromosome

Since each ________ has slight differences in their genetic makeup, each gamete will have a unique genetic makeup.

spindle fiber

During prometaphase I, of the ________ microtubules are attached to the kinetochore proteins at the centromeres.

Microtubules

________ grow from centrosomes placed at opposite poles of the cell.

synaptonemal complex disappears

When the ________, the homologous chromosomes remain attached to each other at the centromere and at the chiasmata.

non sister

The synaptonemal complex supports the exchange of chromosomal segments between ________ homologous chromatids, a process called crossing over.

sister recombinant chromatid

The ________ has a combination of maternal and paternal genes that did not exist before the crossover.

nuclear envelope

As the ________ begins to degrade, the proteins associated with homologous chromosomes brings the pairs close to each other.

II

During anaphase ________, the sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles.

homologous chromosome

At the end of prometaphase I, each ________ is attached to microtubules from both poles, with one ________ facing each pole.Metaphase I.

microtubules

The ________ attach at each chromosomes 'kinetochores.

Nuclear envelopes

________ form around the chromosomes and cytokinesis separates the two cells into four unique haploid cells.

homologous chromosomes

The microtubules move toward the center of the cell and attach to one of the two ________.

II

During prometaphase ________, the nuclear envelopes are completely broken down, and the spindle is fully formed.

II

During metaphase ________, the sister chromatids are maximally condensed and aligned at the center of the cell.Anaphase ________.
