GeneticsCell Division
Quick Answer
Meiosis is a special type of cell division that makes gametes with half the usual number of chromosomes. It also creates genetic diversity.
The Full Story
Meiosis is the division process that produces sperm and egg cells. It consists of two rounds of division after one round of DNA replication, reducing the chromosome number from diploid to haploid. During meiosis, homologous chromosomes exchange segments in crossing over, and chromosomes are shuffled independently into daughter cells. These processes create genetically unique gametes and are essential for sexual reproduction.
Key Facts
1.Meiosis produces haploid gametes
2.It includes crossing over between homologous chromosomes
3.Humans usually make gametes with 23 chromosomes
