Aresearcher is creating pedigrees for a trait he suspects to be dominant in humans. what are some of the likely features of his pedigrees for families with this trait?

A feature of a pedigree that indicate that a certain trait is a dominant trait is that one of the parents always have to have the trait.

There are, however, autosomal dominance and X-linked dominance.

For an autosomal dominant trait: 
- Appears equally frequent in both sexes.
- Both sexes transmit the trait.
- Present in all generations.
- When one parent has the trait and the other doesn't, approximately half of the offspring will present the trait.

For a X-linked dominant trait: 
- Both male and females can present the trait, but more females usually present it.
- Sons with the trait always have a mother that presents the trait as well.
- Daughters with the trait always have either a mother or father that presents the trait, or both.
- Fathers with the trait always have daughters with the same trait.

It may have some of the same features that it’s mother does but, it may have some of the same features that it’s father has as well.
