|Anaphase I||Two chromosomes of each with two chromatids of each homologous pair separate and move toward opposite poles.|
|Telophase I||Chromosomes arrives at the spindle poles|
|Cytokinesis||Cytoplasm divides to produce two cells, each having half the original number of chromosomes|
What are the two main purposes of meiosis 1?
The two broad goals of meiosis are to produce haploid daughter cells (gametes), and to generate variance.
What are the main goals of meiosis?
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
What is the difference between meiosis 1 and meiosis 2?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
What is the difference between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Which of the following is unique to meiosis?
Daughter cells produced in meiosis are genetically different. It is a unique feature of meiosis. Further Explanation: Meiosis is a reductional cell division where the haploid chromosome containing four daughter cells formed.
What cell is formed after meiosis 1?
Both produce two daughter cells from each parent cell. However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell.
How is Meiosis I Different from Meiosis II?
|Meiosis I||Meiosis II|
|Ends with 2 daughter cells||Ends with 4 daughter cells|
What happens during meiosis I?
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.
