Mitosis does its crossing over in prophase
Tetrads don't form in mitosis. Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination. The products of meiosis are gametes which ensure genetic diversity in subsequent generations. In mitosis, the daughter cells are genetically identical to the parent cell. No genetic recombination occurs in mitosis.
chromosomes split and the cell divides The above mentioned two things happen in mitosis also, so the correct answer would be - 1. Exchange of chromatin material by crossing over and 2. Reduction in the number of chromosomes to half.
Meiosis I is similar to mitosis, as both processes involve the separation of homologous chromosomes. In meiosis I, the genetic material undergoes recombination and crossing over, leading to genetic diversity, which does not occur in mitosis.
prophase 1.
Yes they are attached at the centromere and remain identicle until crossing over occurs in prophase 1 of meosis
During prophase in meiosis, homologous chromosomes pair up and undergo crossing over, exchanging genetic material. This process does not occur during mitosis, where individual chromosomes line up and separate without crossing over.
well from what i understand mitosis is just the replication of a cell, a cell divides into two cells and it is not being effected by any other cell so crossing over cant occur Crossing over occurs in meiosis to create diversity in the genetic material so the offspring is neither identical to father or mother. in mitosis it does not occur because the parent cell is making an identical copy of itself, so the DNA does not need to vary.

During prophase I of meiosis, homologous chromosomes pair up and undergo crossing over, where segments of DNA are exchanged between them. This does not occur during prophase of mitosis, where homologous chromosomes do not pair up or undergo crossing over.

Meiosis I is similar to mitosis, as both processes involve the separation of homologous chromosomes. In meiosis I, the genetic material undergoes recombination and crossing over, leading to genetic diversity, which does not occur in mitosis.
In metaphase I of meiosis, homologous chromosomes align at the cell's equator in pairs, while in metaphase of mitosis individual chromosomes align. Additionally, in meiosis I, genetic recombination and crossing over can occur between homologous chromosomes, increasing genetic diversity.
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
Birnkrant 616 - 2006 Crossing Over Part 1 1-2 was released on: USA: January 2006
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.
