_________ are the basic units of inheritance.

• A. Genes
• B. Chromosomes
• C. Gametes
• D. Zygotes

Answer: (A)

Genes are the basic units of inheritance. They are specific sequences of DNA that carry the instructions for making proteins or regulatory elements that shape traits. Alleles, different versions of a gene, explain how offspring resemble or differ from their parents and how traits are passed down through generations. Genes sit on chromosomes, which organize and package genetic material, but the actual unit transmitted across generations is the gene itself. Gametes are the reproductive cells that carry half the genetic material, and zygotes form when those gametes join, restoring the full set of chromosomes. In aquaculture, understanding genes helps explain why selective breeding can enhance desirable traits such as growth rate or disease resistance by combining favorable alleles in future stock.
