A few quick questions on mitosis, how fertilisation and meiosis give variation among siblings, and sex-linked inheritance. Taught in class; use this to check yourself.
Siblings share both parents but are not copies of each other. And why do some conditions show up more in boys?
Your teacher covers these in class. The questions check the basics: what mitosis does, how offspring get their genes, and why sex-linked traits behave differently.

Is it mitosis or meiosis?
A self-test on mitosis, how fertilisation and meiosis give variation, and sex-linked inheritance (AC9S10U01, nodes 2, 5 and 6, taught in class; node 6 a hinge). About 16 minutes.
Open the teacher guide: answers, solutions, slides and a worksheet.
A Quick check: a few questions on what students should know for AC9S10U01 nodes 2, 5 and 6, which you teach in class. It has no board, no clip and no new teaching, and it is optional, so it never holds up course completion. Set the width with ?width=minimum, typical (default) or wider.
Use it as a self-test after your teaching, a starter, or revision. DNA, meiosis and Punnett squares are on screen (nodes 1, 3 and 4). The notation here is XN for the normal allele and Xn for the condition allele; use whichever your class uses, as long as it is consistent.
Keeping the sex chromosomes and the alleles apart in one square. When a student gets lost, ask which letters are chromosomes and which are alleles.
Stretch: Trace a trait such as red-green colour blindness through three generations of a family tree.
Support: Give the Punnett square grid with the parent gametes already written in.
Back in class: family pedigree analysis; a mitosis stages practical or models.
