Instructions for marking the written paper
1. Always use red ink.
2. Put a tick next to each correct answer. Each correct tick is worth one point. Half a
point is not to be given. If a question which is worth two points is answered correctly,
put two ticks.
3. If there is a correct answer to a question which is not included in the marking scheme
you can still accept it. The same principle applies to synonyms. (e. g.: platelets —
trombocytes)
4. The equally acceptable, alternative answers are separated with a backslash (/) in the
marking scheme.
5. At the end of each task add up the points in the grey boxes.
6. At the end of the examination paper fill in the summary table by giving the achieved
score of each task and by adding them up calculate the total score.
7. Mark each correct answer with a tick on the margin in the optional essay. In the
marking scheme only the most important terms and expressions are included in the
correct logical order. You can also accept the answers if they are logically built up
even if this logic is different from the one given in the marking scheme, unless it is
otherwise stated in the given task. In the end, please add up the points of the correct
answers and write them into the appropriate boxes of the summary chart.
In the essay, points can only be given for answers responding to the guiding questions.
8. If the candidate started answering both optional tasks (A and B) act according to the
instructions given under the heading of ‘Important Information’.
9. If the candidate is expected to formulate an answer in full sentences (e.g. reasonings
and explanations) only grammatically correct sentences can be accepted. Do not
subtract points for spelling mistakes but do not accept ambiguous sentences
either.
Good luck for your work!

Within the population of individuals with unattached earlobes a child with attached earlobes
can only be born from the marriage of two heterozygotes. The possibility of such a marriage:
0.333 .0.333 = 0.111
Since the possibility of having a homozygous child from such a marriage is 0.25 the overall
possibility in question: 0.111 . 0.25 = 0.028 (2.8%)
