Solution

To answer the question, we need to understand the definitions of the given options and determine which one refers to the mating of closely related organisms to produce desirable traits.

  1. Inbreeding: Inbreeding refers to the mating of individuals who are closely related, such as siblings or parents and offspring. This can lead to the expression of recessive traits and an increased risk of genetic disorders.

  2. Hybridization: Hybridization involves the mating of individuals from different species or varieties to produce offspring with a combination of traits from both parents. This can result in increased genetic diversity and the potential for new desirable traits.

  3. Karyotyping: Karyotyping is a laboratory technique used to analyze and visualize the chromosomes of an individual. It helps identify any chromosomal abnormalities or genetic disorders.

  4. Crossing-over: Crossing-over is a process that occurs during meiosis, where genetic material is exchanged between homologous chromosomes. This leads to genetic recombination and the creation of new combinations of alleles.

Based on the definitions provided, the correct answer for the mating of closely related organisms to produce desirable traits is (1) inbreeding.
