We inherit characteristics from our parents in the form of genes. A
child at birth possesses a unique combination of genes received
from both parents. This inheritance provides a distinct biological blueprint and timetable for an individual’s development. The study of the inheritance of physical and psychological characteristics from ancestors is referred to as genetics. The child begins life as a single zygote cell (mother’s ovum fertilised by father’s sperm). Zygote is a tiny cell with a nucleus in its center containing chromosomes. These chromosomes with all genes are inherited from each parent in equal numbers.
