THE GENES
Each cell in the human body contains about 25,000 to 35,000 genes. Genes carry information that determines your traits.
THE GENES
Traits are the characteristics you inherit from your parents.For example, if both of your parents have green eyes, you might inherit the trait of green eyes from them.
THE GENES
Genes are kept on chromosomes.
Chromosomes come in pairs, and there can be thousands of genes in one chromosome.
Chromosomes (and genes) are made of DNA.
THE GENES
Chromosomes are inside the nucleus of cells.
The nucleus contains all the information about the cell that it governs. The chromosomes are the information.
THE GENES
In human cells, the nucleus contains 46 chromosomes: 23 from each parent. These chromosomes contain the information about how we are.
For example: chromosomes X and Y decide the sex.
