* Most of the cortico-spinal fibers (about 90%) cross over to the contralateral side in the http://www.answers.com/topic/medulla-oblongata (http://www.answers.com/topic/decussation-of-the-pyramids). Those that cross in the medulla oblongata travel in the http://www.answers.com/topic/lateral-corticospinal-tract. * The remainder of them (10%) cross over at the level that they exit the http://www.answers.com/topic/spinal-cord, and these travel in the http://www.answers.com/topic/anterior-corticospinal-tract. Most of the cortico-spinal fibers (about 90%) cross over to the contralateral side in the medulla oblongata (pyramidal decussation). Those that cross in the medulla oblongata travel in the lateral corticospinal tract. The remainder of them (10%) cross over at the level that they exit the spinal cord, and these travel in the anterior corticospinal tract.
What else can I help you with?
In which process can recombination through independent assortment and crossing over occur?
Recombination through independent assortment and crossing over can occur during the process of meiosis.
Does crossing over occur during mitosis?
No, crossing over does not occur during mitosis. Crossing over is a genetic process that happens during meiosis, specifically during prophase I, where homologous chromosomes exchange genetic material. Mitosis is a different type of cell division that does not involve crossing over.
Where does crossing over occur in the process of mitosis?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
At what stage of mitosis does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
Synapsis and crossing over occur during?
Synapsis and crossing over occur during prophase I of meiosis. During synapsis, homologous chromosomes pair up and exchange genetic material, a process known as crossing over, which increases genetic diversity.
When do stages of meiosis recombination or crossing over occur?
Crossing over occurs during Prophase I.
In which process can recombination through independent assortment and crossing over occur?
Recombination through independent assortment and crossing over can occur during the process of meiosis.
Does crossing over occur during mitosis?
No, crossing over does not occur during mitosis. Crossing over is a genetic process that happens during meiosis, specifically during prophase I, where homologous chromosomes exchange genetic material. Mitosis is a different type of cell division that does not involve crossing over.
Where does crossing over occur in the process of mitosis?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
At what stage of mitosis does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
Pairing of homologues and crossing over occur during?
prophase I
What phase does meiosis crossing over occur?
prophase 1.
How does crossing over incrase phenotypicvariation in a population?
crossing over allows new genes to be made by the crossing over itself or by mutations that occur in the genes as crossing over occurs. since the phenotype is the physical appearance of the gene, the crossing over can change the genotype which can change the phenotype.
Synapsis and crossing over occur during?
Synapsis and crossing over occur during prophase I of meiosis. During synapsis, homologous chromosomes pair up and exchange genetic material, a process known as crossing over, which increases genetic diversity.
In which stage of cell division, mitosis or meiosis, does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis.
Could crossing over occur during the second meiotic division?
No, crossing over occurs during prophase I of meiosis when homologous chromosomes exchange genetic material. The second meiotic division involves separating sister chromatids, so crossing over does not occur.
Can crossing over occur during mitosis?
No, crossing over does not occur during mitosis. It is a process that happens during meiosis, specifically during prophase I. During crossing over, genetic material is exchanged between homologous chromosomes, leading to genetic variation in offspring.
