Meiosis 1 Crossing over and Phase identification

meiosis  Standard Level · Meiosis produces genetic variety via two key processes Meiosis occurs in ovaries and testes, where a single cell divides twice to produce four cells containing half the original amount of genetic information

Both male and female meiosis contribute to non-Mendelian inheritance of parental chromosomes in interspecific plant hybrids  In humans, special cells called germ cells undergo meiosis and ultimately give rise to sperm or eggs Germ cells contain a complete set of 46

Phases of Meiosis Before meiosis, the DNA is replicated, as in mitosis Meiosis then consists of two cell divisions, known as meiosis I and meiosis II In the Phases of meiosis I In meiosis I, cells go through four phases: prophase I, metaphase I
