Spermatids3

• Each secondary spermatocyte will form two spermatids after Meiosis II. (wikipedia.org)
• At the completion of meiosis, four haploid gametes, termed round spermatids, result from the division of every spermatocyte. (jci.org)
• The process of spermatogenesis as the cells progress from spermatogium, to primary spermatocytes, to secondary spermatocytes, to spermatids and to Sperm. (iiab.me)

Called spermatid1

• Making sperm (spermatogensis): primary spermatocyte-then we are going to get a secondary spermatocytes (2) and these each break into two cells called spermatid- has to do more growth to become a spermatozoan (when the spermatid becomes the spermatozoan: this is called spermiogenesis). (memory.com)

Pachytene spermatocytes2

• During mouse spermatogenesis, the mutation frequencies of cells at the different stages, including pachytene spermatocytes, are 5 to 10-fold lower than the mutation frequencies in somatic cells. (wikipedia.org)
• Recombination and separation of homologous chromosomes occurs in pachytene spermatocytes during meiosis I and results in the formation of secondary spermatocytes. (jci.org)

Male gametocyte1

• Spermatocytes are a type of male gametocyte in animals. (wikipedia.org)

Haploid2

• Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes. (wikipedia.org)
• One of the haploid cells that are formed by division of the secondary spermatocytes and that differentiate into spermatozoa. (ontobee.org)

Diploid1

• Primary spermatocytes are diploid (2N) cells. (wikipedia.org)

Undergoes1

• Each spermatocyte undergoes meiosis (maturation phase). (ncertmcq.com)

Meiosis4

• After meiosis I, two secondary spermatocytes are formed. (wikipedia.org)
• The primary spermatocytes within the adluminal compartment will continue on to Meiosis I and divide into two daughters cells, known as secondary spermatocytes, a process which takes 24 days to complete. (wikipedia.org)
• Spermatocytes regularly overcome double-strand breaks and other DNA damages in the prophase stage of meiosis. (wikipedia.org)
• In spermatocytes, HRR events occur mainly in the pachytene stage of meiosis and the gene conversion type of HRR is predominant, whereas in other stages of spermatogenesis the reciprocal exchange type of HRR is more frequent. (wikipedia.org)

Mitosis2

• Spermatogonia going through mitosis to form primary spermatocytes in Grasshopper testes . (iiab.me)
• Finally they stop undergoing mitosis, grow and become primary spermatocytes (growth phase). (ncertmcq.com)

Primary5

• There are two types of spermatocytes, primary and secondary spermatocytes. (wikipedia.org)
• Primary and secondary spermatocytes are formed through the process of spermatocytogenesis. (wikipedia.org)
• The formation of primary spermatocytes (a process known as spermatocytogenesis) begins in humans when a male is sexually matured at puberty, around the age of 10 through 14. (wikipedia.org)
• Primary spermatocytes are arrested after DNA synthesis and prior to division. (wikipedia.org)
• secondary adaptive response (SĔK-ŏn-dăr-ē ad-ap-TĬV ri-SPONS): Immune response observed upon re-exposure to a pathogen, which is stronger and faster than a primary response. (pressbooks.pub)

Spermatogonia1

• Differentiating spermatogonia in mice undergo five mitotic divisions before converting to preleptotene spermatocytes. (jci.org)

Formation of secondary1

• LH promotes Leydig cell secretion of testosterone into the testes and blood, which induce spermatogenesis and aid the formation of secondary sex characteristics. (wikipedia.org)

Spermatogenesis1

• Homologous recombinational repair (HRR) of double-strand breaks occurs in mice during sequential stages of spermatogenesis but is most prominent in spermatocytes. (wikipedia.org)

Cells1

• Although spermatocytes that divide mitotically and meiotically are sensitive to radiation and cancer, spermatogonial stem cells are not. (wikipedia.org)

Division1

• First maturation division is reductional, and produces two secondary spermatocytes. (ncertmcq.com)

Spermatogonia3

• Nucleus of Sertoli cells and germ cells (spermatogonia type A, pachytene primary spermatocyte and round spermatid) were counted in 20 seminiferous tubules per rat (n = 10 animals [group. (thefreedictionary.com)
• Some of the spermatogonia called primary spermatocytes periodically undergo meiosis. (studyrankers.com)
• Primary spermatocytes are produced from dark type B spermatogonia. (medicinequestionbank.com)

Chromosomes4

• Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes. (wikipedia.org)
• The secondary spermatocytes (choice C) are the products of the first meiotic division and contain 23 doubled chromosomes (46 chromatids). (freemcatprep.com)
• A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each. (studyrankers.com)
• On the contrary the two tested doses of cisplatin had a normal effect on spermatocyte chromosomes (germ cells). (phcogj.com)

Second meiotic division1

• The secondary oocyte enters the second meiotic division at ovulation, but gets completed at fertilization. (medicinequestionbank.com)

Oocyte3

• monopolized by one daughter cell, the secondary oocyte. (dokumen.tips)
• The smaller cell is known as the first polar body, while the larger cell is known as the secondary oocyte. (studyrankers.com)
• In females, secondary oocytes are of only one type, i.e., each secondary oocyte has 22 autosomes and one X chromosome (22X). (medicinequestionbank.com)

Males1

• In all animals, males produce spermatocytes, even hermaphrodites such as C. elegans, which exist as a male or hermaphrodite. (wikipedia.org)

Type1

• Spermatocytes are a type of male gametocyte in animals. (wikipedia.org)

Polar body1

• a polar body or secondary polosit cells (n). (dokumen.tips)

Gametes1

• The female gametes are secondary oocytes, which are released from the ovary in a cyclic fashion throughout the reproductive life of a female. (medicinequestionbank.com)

Largest1

• 2. Spermatocytes 1: The largest size, spherical shape, color strong core, lies a short distanceaway from the basement membrane. (dokumen.tips)

Size1

• 3. Spermatocytes II: The size is rather small (1 / 2 x spermatocytes 1), spherical shape,color stronger core, lies the basement membrane further and further away (near lumen). (dokumen.tips)
