**This Powerpoint specifically uses the Cambridge AS Level Biology Syllabus and covers all criteria for – Unit 16 Inheritance
**
Students will be able to -

1 explain the meanings of the terms haploid (n) and diploid (2n)

2 explain what is meant by homologous pairs of chromosomes

3 explain the need for a reduction division during meiosis in the
production of gametes

4 describe the behaviour of chromosomes in plant and animal
cells during meiosis and the associated behaviour of the
nuclear envelope, the cell surface membrane and the
spindle (names of the main stages of meiosis, but not the
sub-divisions of prophase I, are expected: prophase I,
metaphase I, anaphase I, telophase I, prophase II,
metaphase II, anaphase II and telophase II)

5 interpret photomicrographs and diagrams of cells in different
stages of meiosis and identify the main stages of meiosis

6 explain that crossing over and random orientation
(independent assortment) of pairs of homologous
chromosomes and sister chromatids during meiosis produces
genetically different gametes

7 explain that the random fusion of gametes at fertilisation
produces genetically different individuals

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a FREE pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
