What is the total number of chromosomes found in horses?

• A. 78 individual chromosomes, 39 pairs.
• B. 64 individual chromosomes, 32 pairs.
• C. 38 individual chromosomes, 19 pairs.
• D. 72 individual chromosomes, 36 pairs.

Answer: (B)

The correct number of chromosomes found in horses is 64 individual chromosomes, which form 32 pairs. This characteristic chromosome number is vital for proper reproduction and genetic stability in the species. Horses, being diploid organisms, typically have two sets of chromosomes — one set inherited from each parent. Each of the 32 pairs consists of homologous chromosomes, which carry genes that determine various physical and behavioral traits in the species. Understanding the significance of the chromosome number in horses also highlights its implications for breeding and genetic research. The specific pairs of chromosomes ensure that offspring have the appropriate genetic material to develop properly and maintain the species' health and viability.
