SEX CHROMOSOMES / GONOSOMES: is pair 23 – give information of gender of person –XX is female; XY is male. 20min Educator must explain how to identify gender using karyotype chart. Explain to learners that it is the sex chromosomes which determine the sex of a child. Learners must be able to use the autosomes and SPERM CELLS- 22 AUTOSOMES + X or Y CHROMOSOME AFTER MEIOSIS.’ sex chromosomes to determine the sex of an EGG CELL – 22 AUTOSOMES = X or X CHROMOSOME AFTER offspring from educator explanation. MEIOSIS. Explain that gametes are haploid and somatic cells have diploid chromosome numbers.
