Example: Karyogamy is an essential step in the process of fertilization in many organisms.

Definition: The process during cell division where the nucleus divides to form two nuclei, each with the same number of chromosomes as the original nucleus.

Example: During karyokinesis, the genetic material is evenly distributed to the daughter cells.

Definition: Relating to the process of cell division where the nucleus divides into two nuclei.

Example: The karyokinetic process is essential for cell reproduction.

Definition: The study of the structure and characteristics of cell nuclei and their chromosomes.

Example: Karyology is essential for understanding genetic diseases and cell division.

Definition: A clump of genetic material found in the nucleus of a cell that is not dividing, which looks similar to a small structure called a nucleolus.

Example: The karyosome can be observed under a microscope in certain types of cells.

Definition: A visual representation or arrangement of chromosomes in a cell, showing their number, size, and shape.

Example: The scientist prepared a karyotype to study the genetic abnormalities in the patient.

Definition: To classify and arrange the chromosomes of an organism based on their characteristics such as number, size, and shape.

Example: Scientists use karyotyping to analyze the chromosomes of the cells in a sample.

Definition: Relating to the number and appearance of chromosomes in the nucleus of a cell.

Example: The karyotypic analysis revealed the presence of an extra chromosome.

Definition: In a way that relates to the karyotype, which is the number and appearance of chromosomes in the nucleus of a cell.
