Meiosis Practice Problems

During meiosis, homologous chromosomes can exchange genetic material through crossover events. How does this process contribute to genetic diversity?

During which stage of meiosis do homologous chromosomes segregate from each other, which parallels Mendel's law of segregation for autosomal alleles?

How does the protein complex called cohesin ensure proper segregation of sister chromatids in cell division, and what is the role of the enzyme called separase in this process?

The diploid number of humans is 2n = 46. Which of the following happens to a cell at the end of cytokinesis during meiotic cell division?

During the S phase, the DNA must be unwound first to produce a template strand. Which of the following enzymes performs this function?

The crossing over and exchange of genetic material between chromosomes occurs during:

Before anaphase occurs, the cell ensures that chromosomes lined in the equatorial plate are correctly attached to microtubules. This is to ensure that the sister chromatids will split evenly between the daughter cells. This stage is referred to as:

In metaphase, the chromosomes line up in the equatorial plate of the cell. What structure is responsible for holding these chromosomes in place during this phase?

Nondisjunction happens when there is a failure of homologous chromosomes or sister chromatids to separate during meiosis. Which of the following is a consequence of nondisjunction?

Why are hybrids such as mules not capable of producing viable gametes?

If the fruitfly has 8 chromosomes at a diploid state, what is its resulting total number of unique cells following independent assortment during metaphase in meiotic cell division?

Which of the following happens during the anaphase stage?

Synapsis refers to the connection of homologous chromosomes to form a ______.

At the end of meiosis, a total of ___ cells which are ____  are produced.

What does it imply if the recombination frequency is 50%?

At what stage of meiosis does "gene shuffling" happen?
