Here are the key points about the importance of chromosomes:
- Chromosomes contain DNA and carry the genes that determine traits and characteristics. They are
found in the nucleus of cells and contain the genetic instructions that make each species unique.
- The number and type of chromosomes determine the species. For example, humans have 23 pairs of
chromosomes for a total of 46, while mice have 20 pairs for a total of 40.
- Chromosomes are essential for sexual reproduction as they are passed from parents to offspring.
During meiosis, chromosomes pair up and separate, allowing genetic material from both parents to
recombine in offspring.
- Chromosome abnormalities can cause genetic disorders or conditions. Missing or extra chromosomes
