• A Pedigree in a chart of a family's hi&tory with regard to a particular genetic trait. •In a Pedigree imales Femalex by circles. are designated by Squared an • is a particular genetic trait in Dominant, then every child exhibiting the trait will also have at leaxt one parent exhibiting the trait • it a particular genetic trait is parenta of a child exhibiting the the trait [recektive, then both trait may not exhibit • 19 a particular genetic trait ie I Sex-linked only keen in malex it is usually it a particular genetic trait in Autocomal, it appeare in both sexex gairly equally.

EXPLANATION-

• A pedigree is a chart of genetic history of a family over several generations.
• In pedigree , $\square = males$ ,and $\bigcirc = females$
• If the genetic trait is dominant then ,one of the parent must have the genetic trait.Dominant trait does not skip generations.
• If genetic trait is recessive then , neither parent has to have the genetic trait because the can be heterozygous. Recessive trait can skip the generations.
• If most of males in pedigree are affected ,then the trait is sex-linked.
• If it is equal ratio between males and females, then the trait is autosomal.
