SEHS 12: Genetics

Here's the video of the unit presentation:

12.1.1

1

__________ composed of __________

1

What is the primary function of chromosomes?

1

What is the purpose of DNA replication in cell division?

12.1.1
You only need to cover:
DNA Replication
Chromosome
DNA Polymerase (group)
You could cover lagging and leading strands but you're unlikely to need that detail.

1

Which of the following is true of DNA replication?

1

Children inherit __________  from their parents via the ________________________ , with 50% from the mother and 50% from the father (_______  chromosomes each = _______  chromosomes in total) . _____________________  different combinations of these genes from the same parents are possible.

What goes with what?

Draggable item		Corresponding Item
Human characteristics		Phenotype
Genes		Genotype

1

__________ (or __________) are determined by their __________ (the __________).

12.1.1
Try covering each word then each vertical pair (6 boxes in total)

1

Which characteristics are expressed developmentally by genes only?

12.1.1
Try covering both "characteristics" and grouping them. Then cover the examples.

1

Genes code for the production of ________ which are responsible for the development of an individual.

12.1.2
For Transcription and Translation you could try 5 boxes in total:
2 leaving the T and N visible
2 covering the whole word
1 covering both words
As long as you choose "hide 1 guess 1", there will only be 1 in play at a time. 

1

How genes can influence human characteristics:
Genes can be switched on or off depending on ________ factors (gene regulation).

12.1.2
Cover as you like. My suggestions:
turned on and off
gene regulation
athletic performance

12.1.2

12.1.2

1

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?

1

Multiple genes determine measurable characteristics, so it is ________ a single genetic element is associated with athletic performance.

1

Characteristics that are influenced by genetics
Environmental factors that also influence performance

12.1.3

12.1.3
Don't block out the whole word. Leave enough to give yourself a clue but force some thinking.

1

Training maximizes the likelihood of obtaining a performance level with a genetically controlled ceiling.

1

It is possible to scientifically ascertain the relative contribution of genetics or training to elite sporting performance for a variety of sports.

2

Identify two possible benefits of genetic screening in shot put.

1

Identify one possible drawback of genetic screening in shot put.

12.1.4

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?

5

Outline how characteristics of an elite basketball player can be influenced by their genes.
[5]

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!

1

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

1

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.
