Genetics
Heredity
Traits
• the study of heredity
• the passing of traits from parent to offspring
• Characteristics that are determined by genes.

Cell • smallest unit of a living thing.
• looked like tiny cells of a monastery/jail.

Nucleus • dark spot inside cell• control center; the
“brain”

Chromosome • inside the nucleus• made up of a long
strand of DNA• location of genes• humans have 2 of
every chromosome (23 pairs, 46 chromosomes)

Gene • instructions for traits• sections of DNA on
chromosomes• found in pairs• have specific
locations on chromosome

DNA • deoxyribonucleic acid• long strands that
make up genes (instructions)

Robert Hooke
Anton Van Leeuwenhoek
Robert Brown
• Used microscope to view samples of cork
• Gave “cells” their name
• First to see living organisms
• Gave the name “nucleus” to the dark blob seen in cells.
