Question 3 of 13

1

Genes instruct the cells to make proteins needed for your body to work. The strands of DNA are made up of four chemicals that we call bases, along with phosphate and sugar molecules. It is the order of these four different bases along each piece of the DNA strand that determines the protein code.

Select one of the following:

True
False

Explanation

Question 4 of 13

1

Choose the characteristic which is an example of a genetic trait.

Select one of the following:

blue eyes
dyed hair
tatoos

Explanation

Question 5 of 13

8

In some cases, several ❌ work together to determine a feature. A good example of this is ❌ colour. Human eye colour does not follow a simple ❌ of inheritance, because it is ❌ by a ❌ of different genes. As a result, there is a wide ❌ of eyes colours in humans. This is an example of ❌ variation, where there is a wide range of possible ❌.

1

The genetic make up of an individual organism is called the phenotype.

Select one of the following:

True
False

Explanation

Question 7 of 13

3

Tick the correct facts about chromosomes.

Select one or more of the following:

Each chromosome contains hundreds of genes.
Chromosomes occur in triplets.
Human body cells have 46 chromosome pairs.
The sex cells have only one chromosome from each pair.
Offspring get one of each pair of chromosomes from their mother and one from their father, meaning they have two alleles for each gene.

2

Fill the blank spaces to complete the text.

It is possible that both alleles of a gene are the same, in which case the individual is said to be for that trait. If the alleles for a gene in an individual are different, the individual is said to be for the trait.

Explanation

Question 9 of 13

Question 10 of 13

1

Draw a punnett square for a cross between a hairy-toed male (Hh) and a female with hairless toes (hh). What proportion of the offspring would have hairy toes?

Select one of the following:

0.25
0.50
0.75
1.00

Explanation

Question 11 of 13

7

Clones are individuals with ❌ genes. Bacteria, plants and even some ❌ can reproduce ❌ to form clones. In asexual reproduction, only one ❌ is involved, so the offspring has identical ❌ to the parent. As clones have identical DNA, any differences between clones and their parents are likely to be due to the ❌ which they are in, rather than to their ❌.
