Genetic Foundations
-DNA is to small to see but under a microscope it looks like a twisted ladder
-Every living thing has DNA
– A gene is a segment of DNA along the length of a chromosome
-Genes are found on chromosomes and are made of DNA
-Different genes determine the different characteristics or traits of an organism
The Sex Cells
Cell Division
A unique feature of DNA can duplicate itself through a process known as Mitosis
Takes place in regular body cell
Keeps cells living and growing
Gametes of an organism are formed through a cell division known as Meiosis
When sperm and ovum unite at conception the resulting cell is called a zygote
People have a chromosome count of 46
The egg has 23 chromosomes and the sperm has 23 chromosomes
During meiosis gametes (sex cells) undergo a double division
