No, duplication of paired chromosomes occurs during the S phase of interphase before meiosis begins. In meiosis, homologous chromosomes pair up during prophase I.

What will separate in the first division in meiosis one?

Homologous chromosomes will separate in the first division of meiosis 1, moving to opposite poles of the cell in a process called disjunction. This results in the reduction of the chromosome number by half.


How does the appearance of the chromosome change through division?

During cell division, chromosomes condense and become more visible under a microscope as they coil up tightly. The chromosomes then line up along the center of the cell before being pulled apart into two separate sets. Finally, the chromosomes decondense back into chromatin after division is complete.

What must happen before meiosis or mitosis can take place?

Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.


How meiosis reduces the number of chromosomes by half?

Meiosis involves two rounds of cell division (meiosis I and meiosis II), resulting in the formation of four daughter cells with half the number of chromosomes as the parent cell. During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over. This reduces the chromosome number by half in the resulting daughter cells.


What stage of meiosis is the chromosome number reduced?

In Anaphase I


If homologues are separating what phase is this?

If homologues are separating, this is likely occurring during the first division of meiosis, known as meiosis I. Homologous chromosomes separate during anaphase I of meiosis.


What happens during the first division of meiosis that does not happen in meiosis?

In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids


What is the number of chromosomes in daughter cells in humans meiosis?

The number of chromosomes in daughter cells in human meiosis is 23. During meiosis, the number of chromosomes in the parent cells (sperm and egg cells) is halved to produce haploid daughter cells, which contain half the number of chromosomes as the parent cells.


What is the separation of homologous pairs of double chromosomes during meiosis?

Is homologous chromosomes only present in cells that undergo meiosis?

Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
