During the process of meiosis‚ diploid cells split in half‚ forming four haploid cells‚ which each have a single set of chromosomes. These cells are called either gametes or sex cells. Female gametes

In 2003‚ according to National Statistics‚ 71% of boys and 79% of girls achieved 5+A*-C GCSE/GNVQs. These statistics
