A ________ is a Chart That Shows Genetic Relationships Within

Question

A ________ is a chart that shows genetic relationships within a family over several generations.
A) karyotype
B) pedigree
C) Punnett square
D) single-gene disorder map

Accepted Answer

A pedigree is a diagram that shows the pattern of inheritance of a particular trait in a family over multiple generations. It can be used to analyze genetic disorders and track the transmission of genes within a family. A karyotype is a visual of an individual's chromosomes, a Punnett square is used to predict the probability of traits in offspring, and a single-gene disorder map shows the location of genes responsible for particular disorders on a chromosome. None of these options fit the description of a chart showing genetic relationships within a family over several generations.
