Any of the structures into which a chromosome divides during mitosis or meiosis
- A.
Prophase
- B.
Cytokinesis
- C.
Chromatid
Correct Answer
C. ChromatidExplanation
A chromatid is one of the structures into which a chromosome divides during mitosis or meiosis. During these processes, the chromosome replicates and forms two identical chromatids joined together at a region called the centromere. Each chromatid contains the same genetic information as the original chromosome. In prophase, the chromatids condense and become visible under a microscope. Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells. Therefore, the correct answer is chromatid.Rate this question:

A form of cell division happening in sexually reproducing organisms by which two consecutive nuclear divisions (meiosis I and meiosis II) occur without the chromosomal replication in between, leading to the production of four haploid gametes (sex cells), each containing one of every pair of homologous chromosomes (that is, with the maternal and paternal chromosomes being distributed randomly between the cells).
- A.
Tetrad
- B.
Meiosis
- C.
Stem cell
Correct Answer
B. MeiosisExplanation
Meiosis is the correct answer because it is the form of cell division that occurs in sexually reproducing organisms. During meiosis, two consecutive nuclear divisions (meiosis I and meiosis II) occur without chromosomal replication in between. This process leads to the production of four haploid gametes, each containing one of every pair of homologous chromosomes. These chromosomes are randomly distributed between the cells, resulting in genetic variation.Rate this question:

The cells that results from the asymmetric division of an oocyte. In animals and humans, polar bodies are produced every after meiotic division. They are relatively smaller in size due to less cytoplasm compared to the gametocyte that will become the ovum. This is essential so that much of the cytoplasm is available and the chromosomal content is halved at the time of fertilization. The polar bodies will eventually degenerate. In plants, the polar bodies may also be fertilized by a sperm cell (aside from the ovum fertilized by another sperm cell). The fertilized polar bodies will develop and give rise to the endosperm while the fertilized ovum will become the plant embryo.
- A.
Haploid
- B.
Centromere
- C.
Polar bodies
Correct Answer
C. Polar bodiesExplanation
Polar bodies are the cells that result from the asymmetric division of an oocyte. In animals and humans, polar bodies are produced after meiotic division and are smaller in size compared to the gametocyte that will become the ovum. This is important because it allows for more cytoplasm to be available in the ovum and ensures that the chromosomal content is halved at the time of fertilization. The polar bodies eventually degenerate. In plants, the polar bodies can also be fertilized by a sperm cell, and the fertilized polar bodies develop into the endosperm while the fertilized ovum becomes the plant embryo.Rate this question:

Mode of reproduction involving the fusion of female gamete (ovum) and male gamete (spermatozoon), which forms a zygote that potentially develops into genetically distinct offspring.
- A.
Sexual reproduction
- B.
Asexual reproduction
- C.
Cancer
Correct Answer
A. Sexual reproductionExplanation
Sexual reproduction involves the fusion of a female gamete (ovum) and male gamete (spermatozoon), resulting in the formation of a zygote. This zygote has the potential to develop into genetically distinct offspring. This process introduces genetic variation into the population, as the offspring inherit a combination of genetic material from both parents. Asexual reproduction, on the other hand, does not involve the fusion of gametes and does not result in genetically distinct offspring. Cancer is a disease characterized by the uncontrolled growth and division of abnormal cells and is not related to the given description.Rate this question:

- A.
Sexual reproduction
- B.
Asexual reproduction
- C.
Cancer
Correct Answer
B. Asexual reproductionExplanation
Asexual reproduction is a form of reproduction that does not involve meiosis, ploidy reduction, or fertilization. In this process, the offspring is a clone of the parent organism, meaning it is genetically identical to the parent. This type of reproduction is commonly observed in many organisms, such as bacteria, fungi, and plants, where a single parent can produce offspring without the need for a mate. It allows for rapid population growth and the preservation of favorable traits, but it lacks genetic diversity compared to sexual reproduction.Rate this question:

- A.
Crossing over
- B.
Tetrad
- C.
Regulation
Correct Answer
A. Crossing overExplanation
During meiosis, crossing over occurs when two chromosomes pair up and exchange segments of their genetic material. This process happens during synapsis, when the chromatids of homologous chromosomes align and form an X-shaped structure called a chiasma. The chromatids break into segments with matching regions, and these segments are then exchanged between the chromosomes. This genetic exchange leads to genetic diversity in the resulting gametes.Rate this question:

- A.
Anaphase
- B.
Metaphase
- C.
Mitosis
Correct Answer
C. MitosisExplanation
Mitosis is the correct answer because it is the process of cell division where a single cell divides into two identical cells. During mitosis, the chromosomes are duplicated and then separated into two sets, resulting in two cells with the same genetic content as the original cell. This process is essential for growth, repair, and maintenance of the body's tissues. Anaphase and metaphase are stages within mitosis, but they do not encompass the entire process of cell division.Rate this question:

Having the full number of chromosomes normally occurring in the mature germ cell, or half the number in the usual somatic cell
- A.
Centromere
- B.
Haploid
- C.
Chromatid
Correct Answer
B. HaploidExplanation
Haploid refers to having half the number of chromosomes in a somatic cell. In contrast to diploid cells, which have the full set of chromosomes, haploid cells only have one set of chromosomes. This is typically seen in mature germ cells, such as eggs and sperm, where the number of chromosomes is reduced by half through a process called meiosis. Haploid cells are important for sexual reproduction as they combine with another haploid cell during fertilization to form a diploid zygote.Rate this question:

The process occurring in the male gonad of sexually reproducing organism wherein the undifferentiated male germ cells develop into spermatocytes
- A.
Spermatogenesis
- B.
Oogenesis
- C.
Tetrad
Correct Answer
A. SpermatogenesisExplanation
Spermatogenesis is the correct answer because it is the process that occurs in the male gonad (testes) of sexually reproducing organisms. During spermatogenesis, undifferentiated male germ cells called spermatogonia undergo a series of divisions and differentiations to form spermatocytes, which eventually develop into mature sperm cells. This process is essential for the production of male gametes and is responsible for the continuous production of sperm throughout the reproductive lifespan of males. Oogenesis, on the other hand, is the process that occurs in the female gonad (ovaries) and involves the development of ova (eggs). Tetrad refers to a group of four chromatids that are formed during meiosis.Rate this question:
