1. Trait appeared in both the sexes with equal frequency.
2. Both sexes are transmitting the trait to their offspring.
3. Every affected offspring has an affected parent.
4. Here, if one parent is affected and the other parent is unaffected, then approximately half of
the offsprings are affected.
5. Unaffected parents are not transmitting the trait.
6. The trait is not skipping the generations..
