A pedigree shows a marriage between two parents, who are both affected by a disorder (their symbols are shaded). This couple has 4 sons. Two of the sons are normal, and the other two have the disorder. This means the disorder is passed on as an _______________ trait.
What is dominant?
400
A possible trait
What is allele

When the phenotype is a mixture of the two alleles
What is incomplete dominance

A pedigree shows four generations of a family tree. When looking at the pedigree, you notice that the only symbols that are shaded in are the males. This indicates that the type of inheritance is most likely...

A couple has three children: a 14-year-old daughter and two sons that are 12 and 10 years old. If the mother and daughter are both known to have a genetic disorder, what would the pedigree of this family look like?
