Human Reproduction


Hereditary
Children inherit their
parents’ features
such as straight hair
and fair skin.

Humans reproduce by giving birth to their children.
Children inherit features such as iris colour, skin colour and type of hair from their parents or
ancestors.


Human Growth

Since birth, we go through changes in height, weight and size.

2 months 6 months 4 years 8 years














Weight = 6 kg Weight = 9 kg Weight = 19 kg Weight = 27 kg
Height = 50 cm Height = 70 cm Height = 95 cm Height = 115 cm

Growth among individuals are different although they are of the same age.
