Do homologous chromosomes pair up during metaphase 2 as they do in metaphase 1?
No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.
What is is the difference between metaphase 1 and 2?
Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.
During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?
It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.
During metaphase II, do homologous chromosomes pair up as in metaphase I?
No, during metaphase II of meiosis, homologous chromosomes do not pair up as they do in metaphase I. Instead, individual chromosomes line up along the metaphase plate.
Bivalents align at metaphase plate?
Metaphase 1
Which cell has a single line of chromosomes?
A gamete, such as a sperm cell or an egg cell, has a single set of chromosomes, which is half the normal number found in somatic cells. This single set is created through a process called meiosis, which ensures genetic diversity during sexual reproduction.
How does metaphase in meiosis differ from metaphase in mitosis?
In metaphase of meiosis, homologous chromosomes line up in pairs, while in metaphase of mitosis, individual chromosomes line up singly.
Differences between metaphase 1 and metaphase 2?
1. In metaphase 1 spindle formation is completed In metaphase 2 spindle formation take place 2. Bivalent are involved in metaphase 1 Bivalents are not involved in metsphase 2
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
Which phase is known as the organization phase in mitosis?
Metaphase!
What phase are the chromosomes lined up on the equatorial plate?
The chromosomes are lined up at the equatorial plate during metaphase of mitosis and metaphase II of meiosis. This alignment ensures that each chromosome is properly attached to the spindle fibers before they separate and move to opposite poles.
What are the differences in the occurrence and significance of metaphase in meiosis compared to mitosis?
In meiosis, metaphase occurs twice (metaphase I and metaphase II) while in mitosis, it occurs only once. The significance of metaphase in meiosis is to ensure proper separation of homologous chromosomes in metaphase I and sister chromatids in metaphase II, leading to genetic diversity. In mitosis, metaphase ensures accurate alignment of chromosomes for equal distribution to daughter cells, maintaining genetic stability.
