Gaby's+Pedigree

==The //Characteristic// that is shown in my pedigree is the eye color. I have 13 family members here. The dotted lines that are going to the 3 girls from their mom means that I'm not related to their mom. Pedigrees are useful to use to study about genetics because you will know how people got their hair,eye or skin color. It's very easy to study because we already know we get them from our parents,grandparents,siblings,cousins, and even aunts/uncles. Now I will talk about what is the dominant trait in my pedigree. The //dominant// //trait// in my pedigree is my dad and his ex-wife, they both have different color eyes. He has dark brown eyes and she has medium brown eyes.The people in my pedigree are my family members and my mother's parents both have dark brown eyes. My mother has medium brown eyes, my big sister has dark brown eyes and I have the same to also my little brother. My father's parents both have dark brown eyes. My father has dark brown eyes just like them. Before I was born my dad married a lady before he met my mom. They had 3 daughters. Those 3 girls all have dark brown eyes like my dad.Their mom has medium brown eyes. However I do not know what color her parents eyes are so I didn't put her parents in my pedigree. My mother's parents and my father's parents are all //homozygous// because they have the same eye color. //Homozygous// means a //trait// that has two //dominant// pairs or two //recessive// pairs. I hope you enjoyed seeing my pedigree of my family members.==
