What can be used to trace a trait through a family?
A pedigree is a genetic representation of a family tree that diagrams the inheritance of a trait or disease though several generations. The pedigree shows the relationships between family members and indicates which individuals express or silently carry the trait in question.
What is it called when traits are passed down through family?
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
How is a trait passed on?
Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.
What is the family trait?
In biology and genetics, family traits are the traits in which the family members share — meaning, these traits are alike and expressed among the family members. This likeness is largely due to the genes that they inherited from their parents. Inherited traits are genetically determined.
How do you make a family characteristic tree?

How do we inherit traits from our parents?
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
How traits are transmitted from parents to offspring?
The characteristics that are transmitted from parents to offspring are present in genes. Genes are present on chromosomes. The human cell contains 23 pairs of chromosomes. The trait is one of the characteristics determined by one or more genes.
How do parents pass on traits to their offspring?
Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB or O.
