What is the site of crossing over between two non-sister chromatids?
Chiasma - The microscopically visible site where crossing over has occurred between chromatids of homologous chromosomes during prophase I of meiosis.
What is the difference between prophase I and prophase II of meiosis?
Prophase 1 vs Prophase 2 of meiosisDURING PROPHASE I:Crossing over happens in chromosomes where genetic information is swapped from chromosome to another at a chiasma (chiasmata for multiple crossing over sections)Cell is Diploid 46 chromosomesDURING PROPHASE II:No Crossing over at this point, as it has already happened during prophase I.Cell is Haploid 23 chromosomes
What is the x shaped structure at the bottom of the brain below the hypothalamus and called the 'optic?
chiasma
What is the difference between crossing over and chiasma?
Synapsis is the process in which the genetic material is exchanged between two homologous non sister chromatids (the pair of chromosomes which are same in shape,size but not identical) whereas chaisma is the actual site where synapsis occur.
What term belongs with synapsis tetrads and chiasmata?
crossing over
What is the difference between prophase 1 and 2?
DURING PROPHASE I:Crossing over happens in chromosomes where genetic information is swapped from chromosome to another at a chiasma (chiasmata for multiple crossing over sections)Cell is Diploid 46 chromosomesDURING PROPHASE II:No Crossing over at this point, as it has already happened during prophase I.Cell is Haploid 23 chromosomesRead more: What_is_the_difference_between_prophase_I_and_prophase_II_of_meiosis
Chiasmata form between.?
Sister chromatids
What is mitotic chiasma?
chiasma occurs in meiosis. Fascinating that I didn't answer this question but it's attributed to me so I guess I'll add some detail. Chiasma means crossing/intersecting and are the points where recombination occurs duting meoisis. (Crossing over does not occur in mitosis). Chiasma(singular) or chiasmata (plural) are formed during prophaseof meiosis I duing recombination and hold homologous chromosomes together at the sites where the exchanges of genetic material occur. These "connections: remain in place until until the chromosomes seperate during anaphase.
What is the site of crossing over between two non-sister chromatids?
Chiasma - The microscopically visible site where crossing over has occurred between chromatids of homologous chromosomes during prophase I of meiosis.
What phase are sex cells produced?
It is formed during anaphase. Anaphase is the third stage. You can remember PMAT.P- ProphaseM- MetaphaseA- AnaphaseT- Telephase

What is optic tract?
An Optic Tract is the pathway between the optic chiasma and the brain.

What is the difference between crossing over and chiasma?
Synapsis is the process in which the genetic material is exchanged between two homologous non sister chromatids (the pair of chromosomes which are same in shape,size but not identical) whereas chaisma is the actual site where synapsis occur.
