How does a geneticist use pedigrees?

Question

to trace the inheritance of traits in humans

to prove that sex-linked traits are caused by codominant alleles

to create genetic crosses

to replicate identical strings of DNA

Answer 1

Geneticists use pedigrees to trace the inheritance of traits in humans by studying patterns of inheritance within families over multiple generations. This allows geneticists to determine if a trait is inherited in a dominant, recessive, or other manner, as well as to identify any genetic disorders that may have been passed down through generations. Pedigrees can also be used to track the transmission of specific genetic markers or alleles within a family tree. Overall, pedigrees are a valuable tool for geneticists in studying how genetic traits are passed down and understanding the underlying mechanisms of inheritance.
