Grade 12 Term 1 practical assessment on meiosis using eight labeled human-cell micrographs (A to H). Students identify meiotic phases (Micrographs B, D, E, F, and G), describe chromosome behaviour such as separation into opposite poles and chromosome number reduction, and compare similarities and differences between micrographs. The task includes counting chromosomes and DNA sets at specific stages, naming body locations for the cells, and drawing a complete labeled diagram for a specified phase using a given diploid number.

FAQs

What is the purpose of studying micrographs A to H in this practical?

To use knowledge of meiotic phases and chromosome behaviour in human cells to answer targeted questions based on each micrograph.

Which phases of meiosis are students asked to identify from different micrographs?

Students identify specific phases for Micrograph B, D, E, F, and G by observing features shown in each image.

What type of diagram must be produced in the practical?

A complete, labeled line diagram of the identified meiotic phase is required, using a given diploid number (stated as 6 in the question).
