Chromosomes that possess different genes.Group of answer choiceshomologous chromosomesnonhomologous chromosomes

Answer to the Question

Chromosomes that possess different genes are referred to as nonhomologous chromosomes.

Explanation

1. Definition of Chromosomes:

   • Chromosomes are structures within cells that contain DNA. They carry genetic information in the form of genes.

2. Homologous Chromosomes:

   • Homologous chromosomes are pairs of chromosomes that have the same structure and sequence of genes. They pair up during meiosis, each coming from one parent, and contain the same types of genes but may have different alleles.

3. Nonhomologous Chromosomes:

   • Nonhomologous chromosomes are those that do not have the same genes or are not related in terms of genetic content. They can belong to different chromosome pairs and generally cannot pair up during meiosis.

In summary, the distinction is based on the presence or absence of the same genes on the chromosomes. Nonhomologous chromosomes carry different genes, while homologous chromosomes share similar genes.
