a. chromatids do not separate at the centromere in anaphase I.
b. centromeres do not exist in anaphase I.
c. crossing-over occurs only in anaphase of miitosis
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
Crossing over occurs during Prophase I of meiosis.
I think mitosis because mitosis involves growing which the plant is doing.... sorry if I'm wrong!
DNA replication is technically not part of mitosis. Mitosis is simply the splitting of the nucleus. DNA replication however is part of the interphase, which is part of the cell cycle. The DNA replication is also known as the S phase in the interphase. In this part, the DNA is replicated creating two sets of all genetic information.
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
No, prometaphase is a stage in mitosis, not meiosis. In meiosis, there is a prophase I stage that is similar to prometaphase in mitosis.
they both have a prophase and an anaphase.
Mitosis does its crossing over in prophase
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
During mitosis, chromosomes are in their most condensed form during metaphase
In mitosis, the phases are prophase, metaphase, anaphase, and telophase. In meiosis, the phases are similar but with two rounds of division: prophase I, metaphase I, anaphase I, telophase I, followed by prophase II, metaphase II, anaphase II, and telophase II.
They have many similar steps they both have a prophase and an anaphase
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
The phases found in both meiosis and mitosis are prophase, metaphase, anaphase, and telophase. In meiosis, there are two rounds of division (meiosis I and meiosis II), while mitosis only involves one round of division.
