How do you crossbreed fruits?
One way hybrid fruit varieties are created is by the cross-pollination of flowers from two different fruit trees. This can happen in nature when the wind, birds and bees spread pollen naturally. You can also do this by hand by taking a small paintbrush and painting over each bloom on two different trees.

What foods are genetically modified?
Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism.
How are blood oranges made?
The distinctive red colouring of blood oranges is due to the presence of naturally occurring pigments called anthocyanins. Raspberries, blueberries and black rice are amongst the most common foods where we find anthocyanins . They are very common to many flowers and fruits but just not in citrus.
