Sheep graze on the dry lake bed of Lake George, near the Australian capital city of Canberra, March 14, 2005. Drought conditions worsened slightly in the Australian state of New South Wales last month, threatening crops, the state government said on Monday. The main summer crops being pressured are cotton and feed grain sorghum, while soybeans were also affected. NO RIGHTS CLEARANCES OR PERMISSIONS ARE REQUIRED FOR THIS IMAGE.

Meiosis, SEM

Meiosis. Coloured scanning electron micrograph (SEM) of chromosomes during metaphase (I) of meiosis (gamete formation). Chromosomes consist of deoxyribonucleic acid (DNA) and proteins. During meiosis four daughter nuclei are formed from one parent nucleus after two stages of nuclear division. Meiosis occurs only in the sex cells (gametes) of the testes and ovaries. At metaphase (I) pairs of homologous chromosomes line up along the centre of the cell ready to be separated during anaphase (I). Separation results in two cells with half the usual number of chromosomes. The full complement is restored when two gametes fuse during fertilisation.
