Meiosis is broken up into 2 phases. This include meiosis 1 and meiosis two. After the meiosis 1 phase, prophase 1 begins.

∙ 10y agothe stage is prophase one and the result is that chromosome pairs brake up and share genes

During meiosis the process of crossing over results in new combinations of alleles because?
genetic material is exchanged between chromosomes during this process.
What is the important event during meiosis that results in genetic variation?
Crossing-Over
Mitosis results in two cells whereas meiosis results in one cell?
Mitosis results in two identical daughter cells whereas Meiosis results in four haploid daughter cells. The cells in meiosis are not identical due to crossing-over (exchange of chromosome segements) during the first phase .
What is it called when homologous chromosomes trade alleles?
Crossing-over is when segments of homologous chromosomes switch places. This process occurs during prophase I of meiosis and results in recombinant chromosomes. This adds to the variation seen in offspring.
How do you think crossing over affects the number of different types of gametes that are formed?
You get four choices of gene, of which two are randomly selected. Although sometimes these genes are the same, often they are not all identical. this results in different genotypes and therefore phenotypes being experienced.
The process of meiosis never results in the formation of a?
The process of meiosis never results in the formation of a Diploid.
During meiosis the process of crossing over results in new combinations of alleles because?
genetic material is exchanged between chromosomes during this process.
What is the process of division that results in the formation of cells with half the usual number of chromosomes?
The process of meiosis.
In animals the process which results in haploid gametes is known as?
Meiosis
What are produced during the process of meiosis?
Meiosis results in four genetically nonidentical daughter cells.
What is the important event during meiosis that results in genetic variation?
Crossing-Over
Four genetically different cells is the results of what process?
meiosis
Mitosis results in two cells whereas meiosis results in one cell?
Mitosis results in two identical daughter cells whereas Meiosis results in four haploid daughter cells. The cells in meiosis are not identical due to crossing-over (exchange of chromosome segements) during the first phase .
What results from the process of crossing-crossing during prophase 1?
During crossing over, the pairs of homologous chromosomes exchange pieces of their sister chromatids with one another. This process results in every sister chromatid being genetically different from one another. Eventually, meiosis II results in four non-identical haploid cells called gametes, each containing one set of chromosomes. Crossing over during prophase I greatly increases the possible genetic combinations for an offspring.
What is the process of cell division that results in the formation of cells with half the usual number of chromosomes?
The process of meiosis.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What Process results in the formation of gametes?
Gametes are produced by a type of cell division called meiosis. Meiosis results in four daughter cells each with half the number of chromosomes of the parent cell.
