The failure in the separation of the homologous chromosomes due to meiotic error is known as:

Correct answer: A. Non-disjunction

  • A. Non-disjunction
  • B. Heteroploidy
  • C. Monoploidy
  • D. Polyploidy
  • E. Aneuploidy

Explanation

The failure in the separation of homologous chromosomes due to meiotic error is known as "Non-disjunction." Here are explanations for each of the options:1. Non-disjunction: Non-disjunction is a meiotic error in which chromosomes do not separate correctly. It can lead to one of the daughter cells receiving an extra chromosome, while the other gets one less, resulting in aneuploidy.2. Heteroploidy: Heteroploidy refers to a condition in which there is an abnormal number of chromosomes in an organism's cells. This term can be used more broadly and includes both aneuploidy (due to non-disjunction) and polyploidy.3. Monoploidy: Monoploidy is a condition in which an organism has only one set of chromosomes (half the usual number) in its cells. This is relatively rare in animals but more common in some plants.4. Polyploidy: Polyploidy is a condition in which an organism has more than two complete sets of chromosomes. It can result from errors in meiosis, such as the failure to divide during cell division, or through hybridization of two different species.5. Aneuploidy: Aneuploidy is a condition characterized by an abnormal number of chromosomes in an organism's cells. It is typically caused by non-disjunction during meiosis, leading to cells with an extra chromosome (trisomy) or one less chromosome (monosomy).So, the specific term for the failure in the separation of homologous chromosomes due to meiotic error is "Non-disjunction," which can result in aneuploidy.
