Is disploid the second stage of meiotic division?
No, "disploid" refers to a state where an organism has two sets of chromosomes. Meiotic division is a process that produces gametes with half the number of chromosomes, known as haploid cells. So, disploid is not the second stage of meiotic division.
Is secondary spermatocyte haploid or diploid why?
Secondary spermatocytes are haploid because they result from the first meiotic division in male germ cells, which reduces the chromosome number by half. This process includes homologous chromosomes separating, leading to the formation of haploid daughter cells.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.
Meiosis in the male mammals result in the formation of?
The primary spermatocyte is diploid(2n) and after first meiotic division it will produce 2 haploid(n) secondary spermatocyte and these in turn after second meiotic division will produce 2 more haploid secondary spermatocyte. Therefore by the end of Meiosis one will have 4 haploid secondary spermatocyte or spermatids.
What type of cell division produce the sperm and egg cell?
it is formed by meiosis. At first the spermatazoa go through mitosis making two spermatocytes. which then goes through meiosis producing 4 spermatids which then go through spermogenisi n make 4 sperm cells

The first meiotic division of an immature egg occurs during the?
The first meiotic division of an immature egg occurs during the process of oogenesis. Meiosis I results in the formation of two haploid cells with half the number of chromosomes as a diploid cell. These cells are referred to as secondary oocytes.
What feature of the chromosome complement is reduced int the first meiotic division and kept equal in the second?
The chromosome number is reduced by half in the first meiotic division, going from diploid to haploid, while the chromosome arms remain the same. In the second meiotic division, the chromosome number remains the same, but the sister chromatids are separated resulting in haploid daughter cells.
Is secondary spermatocyte haploid or diploid why?
Secondary spermatocytes are haploid because they result from the first meiotic division in male germ cells, which reduces the chromosome number by half. This process includes homologous chromosomes separating, leading to the formation of haploid daughter cells.
How does second meiotic division different from meiotic division?
The second meiotic division, or meiosis II, differs from the first meiotic division (meiosis I) primarily in that it resembles a typical mitotic division. In meiosis I, homologous chromosomes are separated, reducing the chromosome number by half and leading to the formation of two haploid cells. In contrast, meiosis II involves the separation of sister chromatids in each of the haploid cells produced during meiosis I, resulting in a total of four haploid daughter cells, each with a single set of chromosomes. Additionally, meiosis I includes genetic recombination, while meiosis II does not.
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Which of the two meiotic divisions is similar to the first mitotic division?
Yes, in that the sister chromatids of the homologous chromosomes separate into four new daughter cells. However, the result is four genetically non-identical daughter cells with only one set of 23 chromosomes.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.

Therefore by the end of Meiosis one will have 4 haploid secondary spermatocyte or spermatids.
What is oogenessis?
This is the process by which eggs (ova) are made.It begins with the primordial germ cells (also called oogonium) which are diploid (have the full set of paired chromosomes). They divide by mitosis to produce primary oocytes. Then a primary oocyte undergoes a first meiotic division creating a secondary oocyte and a first polar body (which dies). Then after the second meiotic division of the secondary oocyte, an ootid (now haploid - i.e. has full set of unpaired chromosomes) results, along with a second polar body (which dies just like the first one). The ootid then develops into an ovum (egg).
What is produced from diploid germ cells by meiosis?
4 Haploid gametes. In Meiosis, germ cells first undergo a mitosis like division which produces 2 diploid germ cells. After that division, they undergo a second division in Meiosis 2, without first replicating their chromosomes. The end result is 4 haploid gametes.
What type of cell division produce the sperm and egg cell?
it is formed by meiosis. At first the spermatazoa go through mitosis making two spermatocytes. which then goes through meiosis producing 4 spermatids which then go through spermogenisi n make 4 sperm cells
