Which characteristics are expressed developmentally by genes only?
Genes code for the production of ________ which are responsible for the development of an individual.
How genes can influence human characteristics:
Genes can be switched on or off depending on ________ factors (gene regulation).
How genes can influence human characteristics:
Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription. What is transcription?
Multiple genes determine measurable characteristics, so it is ________ a single genetic element is associated with athletic performance.
Drag and drop in to categories:
nutrition
flexibility
physical training
muscle fibre type
lung capacity
climate
anaerobic threshold
height
technological aids
Characteristics that are influenced by genetics
Environmental factors that also influence performance
Training maximizes the likelihood of obtaining a performance level with a genetically controlled ceiling.
It is possible to scientifically ascertain the relative contribution of genetics or training to elite sporting performance for a variety of sports.
Identify two possible benefits of genetic screening in shot put.
Identify one possible drawback of genetic screening in shot put.
The syllabus also asks you to be aware of:
ethical implications of involuntary exclusion from, or discrimination in, one or more sports
ethical implications of discrimination beyond sport, for example, in employment
What do you think this means?
Outline how characteristics of an elite basketball player can be influenced by their genes.

In the hint, you will find the mark scheme and examiners' report.
It is important that you try to answer this before checking the mark scheme. If you find it uncomfortable, that's great! Sometimes learning hurts a bit!
Which term is defined correctly?
This is a nice question to spend a bit of time investigating the alternative options.
In fact, I'll tell you what - the answer is C. There you go, easy! Now, we could click C and move on, but we don't improve our chances in the final exam with that. Try to use it as an opportunity to discover more.
For example, here's a link to show why the answer in A is weird!
Move on when you're happy you understand why the answer is C
How can genes influence human characteristics?
I. Single genes always determine measurable human characteristics.
II. Genes affect the development of an individual.
III. Genes can be switched on by external factors.
Using sporting examples, discuss the contribution of genetic factors to potential success.

Again, mark scheme in hints.
