The chromosomes are first replicated during interphase. In meiosis I, the homologous chromosomes first pair (synapse) with one another. During synapses, pieces of the chromatids can be exchanged between the homologues. The homologous chromosomes are separated by the end of meiosis I.
In meiosis II, the chromatids are separated from each other, four haploid daughter cells each with single stranded chromosomes are formed.
If it is a male, four sperm are formed. In females, one egg and four polar bodies are formed.

∙ 14y agoThe chromosome pairs line up next to each other in the center of the cell. The pairs separate from each other and move to opposite ends of the cell. Two cells form, each with half the number of chromosomes. Each chromosome is still double-stranded.

Name and briefly describe the stages of the two meiotic divisions of meiosis?
the stages of the two meiotic divisions of meiosis?
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
How would you describe the process of meiosis?
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
What happens to chromosomes during Meiosis 2?
the chromosomes pairs line in the center of the cell the chromosomes pairs line in the center of the cell
What happens at the conclusion of meiosis 1?
Homologous chromosomes are separated.
What happens to chromosomes for meiosis to start?
The chromosomes divide.
What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
Name and briefly describe the stages of the two meiotic divisions of meiosis?
the stages of the two meiotic divisions of meiosis?
What happens to the chromosomes of a cell in order for meiosis to the begin?
They mate.
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
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
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 in anaphase in meiosis?
Chromosomes move to opposite poles of the cell.
What happens to the chromosomes in a cell in order for meiosis to begin?
They must double
Does chiasmata occur in mitosis?
no, it happens in meiosis, it is when the bivalent chromosomes cuts and rejoins so that there is variability in the 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.
How would you describe the process of meiosis?
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
