The particular array of chromosomes that an individual possessed is called its:

Correct answer: C. Karyotype

  • A. Genotype
  • B. Phenotype
  • C. Karyotype
  • D. Genome

Explanation

The correct answer is Karyotype. A karyotype is a visual profile of an individual's chromosomes, showing the number and appearance of chromosomes, including their size, shape, and any abnormalities. It is often used in genetic testing to identify chromosomal disorders.The term Genotype refers to the specific set of genes an organism carries, which influences its traits but doesn't specifically denote the chromosomal structure.Phenotype describes the observable characteristics or traits of an organism, which are influenced by both its genotype and environmental factors.Genome refers to the entire set of genetic material in an organism but doesn't focus on the physical arrangement or appearance of chromosomes as a karyotype does.
