Question

What results in the formation of chiasmata?

• A. Exchange of parts of paired homologous chromosome
• B. Exchange of part of unpaired non-homologous chromosome
• C. Duplication of parts of paired homologous chromosome
• D. Loss of parts of unpaired non-homologous chromosome

Answer 1

Answer:

A. Exchange of parts of paired homologous chromosome

• Exchange of parts of paired homologous chromosomes.

• This process, known as crossing over, forms chiasmata, which hold homologous chromosomes together during meiosis and allow them to separate and form haploid gametes.
