The Singapore-Cambridge General Certificate of Education Advanced Level (or Singapore-Cambridge GCE A-Level) is a GCE Advanced Level examination held annually in Singapore and is jointly conducted by the Ministry of Education (MOE), Singapore Examinations and Assessment Board (SEAB) and the University of Cambridge Local Examinations Syndicate (UCLES).

Meiosis is a round of two cell divisions that results in four haploid daughter cells that each contain half the number of chromosomes as the parent cell. [10] It reduces the chromosome number in a germ cell by half by first separating the homologous chromosomes in meiosis I and then the sister chromatids in meiosis II .
During meiosis, homologous recombination can produce new combinations of genes as shown here between similar but not identical copies of human chromosome 1. Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded ...
The A-level (Advanced Level) is a subject-based qualification conferred as part of the General Certificate of Education, as well as a school leaving qualification offered by the educational bodies in the United Kingdom and the educational authorities of British Crown dependencies to students completing secondary or pre-university education.

A 2007 report by Robert Coe compared students' scores in the ALIS ability test with equivalent grades achieved in A-level exams over a period of approximately 20 years; he found that students of similar ability were achieving on average about 2 grades higher than in the past. In the case of maths it was nearer to 3.5 grades higher. [42]
Synapsis or Syzygy is the pairing of two chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis. When homologous chromosomes synapse, their ends are first attached to the nuclear envelope.
