Genes can come in two different forms or alleles. From this genotype, you will then have the detailed instructions to make a sketch of a human face.Д«efore you begin, you should know a few more things about how genes determine your appearance. You will drop these chromosomes from above your head and they will randomly mix in different ways giving you a genotype. One set is labeled male chromosomes while one is labeled fema le chromosomes. In this activity, you will be given two sets of chromosomes. This genotype then determines your physical appearance, which is called your phenotype. The genes that you have in your body right now make up your genotype. These pairs of genes then determine certain physical features or traits.

Since you have two pairs of chromosomes, you also have two pairs of genes, one from your fath er and one from your mother. These sections of DNA th at contain information that determine your physical features are called genes. Within these 23 pairs of chromosomes, there ar e certain sections that determine different physical features.

Your mother and father each donate 23 chromosomes, which pair up to give you your full set of 23 chromosomes. These chromosomes are large bundles of tightly packed DNA. Human DNA comes in 23 pairs of packages called chromosomes. Some of your features may look nothing like your motherвЂ™s or fatherвЂ™s, we will see why this occurs in the activity. Half of the DNA used to create your body came from your mother while the other half came from your father. This is why some of your physical features may resemble your motherвЂ™s while some may resemble your fatherвЂ™s. The reason is that your DNA is a mixture of your mother and fatherвЂ™s DNA. If your DNA came from your parents and DNA determines your appearance, why do you not look exactly like your mother or father? It turns out that the DNA in your body came almost directly from your mother and father. Did you know that your DNA determines things such as your eye color, hair color, height, a nd even the size of your nose? The DNA in your cells is respons ible for these physical attribute as well as many others that you will soon see. DNA contains all the information needed to build your body.
