How many chromosomes are there at the start of meiosis?
5
What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
What happens to the chromosomes of a cell in order for meiosis to the begin?
They mate.
How many cells does meiosis start with?
Meiosis starts with one cell that has a diploid number of chromosomes, which means it has two sets of chromosomes.
What happens to the chromosomes number by the end of meiosis?
The chromosome number at the end of meiosis is half of the parent cell
What happens to the chromosomes in a cell in order for meiosis to begin?
They must double
What happens in anaphase in meiosis?
Chromosomes move to opposite poles of the cell.
What happens during meiosis that results in a defect characterized by the deletion of a chromosome?
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
What happens to the remaining chromosomes from the last division in meiosis?
In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.
What happens to the number of chromosomes during meiosis?
During meiosis, the number of chromosomes is halved. This process results in the formation of sex cells (sperm and egg) with half the number of chromosomes as the parent cell.
How many times do chromosomes make copies of themselves during meiosis?
Chromosomes make copies of themselves once during meiosis. This occurs during the S phase of interphase, which happens before meiosis I.
What is the first thing chromosomes do in meiosis?
In meiosis, chromosomes replicate during interphase before the start of cell division. This process ensures that each daughter cell will receive the correct number of chromosomes.
