Alleles cross during meiosis, specifically in a process called crossing over. During prophase I of meiosis, homologous chromosomes pair up and exchange genetic material, creating new allele combinations. This increases genetic diversity in offspring.

FAQs & Answers

  1. What happens during crossing over? During crossing over, homologous chromosomes exchange segments of genetic material, leading to new allele combinations.
  2. Why is genetic diversity important? Genetic diversity is crucial for the adaptability and survival of species, as it allows for variations that can enhance resilience to environmental changes.
  3. When does meiosis occur? Meiosis occurs during the formation of gametes (sperm and eggs) in sexually reproducing organisms, enabling genetic variation in offspring.
  4. What are alleles? Alleles are different versions of a gene that can exist at a specific locus on a chromosome, contributing to individual traits in an organism.
