Genetic diversity allows populations to adapt to changing environments. đź“Ą How to Save These Meiosis Notes
Meiosis is a two-step division process that reduces the chromosome number by half. It transforms one diploid cell (2n) into four unique haploid cells (n). Germ cells (testes and ovaries). Purpose: Sexual reproduction and genetic variation. Result: Four non-identical daughter cells (sperm or eggs). 🔍 Key Stages of Meiosis meiosis pdf notes pdf download
Maintains the constant chromosome number (46 in humans) after fertilization. Genetic diversity allows populations to adapt to changing

Homologous pairs align at the metaphase plate. Independent assortment ensures a random mix of maternal and paternal chromosomes.
Homologous chromosomes are pulled to opposite poles. Sister chromatids remain attached. Telophase I & Cytokinesis: Two haploid daughter cells form. Meiosis II: The Equational Division
