GENETICS
• Genetics – study of how traits are passed
from parent to offspring
• Genetics - is a field of study that deals with
heredity.
• HEREDITY - Characteristics that a child
receives from both parents
The Cell
The basic unit of life
Two distinct areas of cell
 Cytoplasm – the major portion of the protoplasmic
substance contained in the cell membrane
 Nucleus – the dark staining body within the
cytoplasm

The Cell
 Prokaryotes
– like bacteria and blue-green algae
There is no nuclear membrane that separates the
nuclear material from the cytoplasm

Eukaryotes – A nuclear membrane separates the
genetic material from the cytoplasm
- These eukaryotes include the majority of living species
and multicellular organisms
