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.

RFLP = Restriction fragment length polymorphismWe can say that an individual has a recombination when we see that in RFLP there are two bands. One in normal migration, and one in the pathologic migration.In generation III we can see it in individual 1, 3, 5, 7, 8, and 10. Any modification of the DNA sequences (mutation, addition, deletion) frequently rearranges the restriction sites. During the action of restriction enzymes, the size of the restriction fragments is then modified, and the fragments are then separated differently according to their size by electrophoresis: a polymorphism is observed.
Answer:
a.) is chemical because know the sugar and water are fused together and the chemical com-bond changed
b.) physical, because they will not mix
Explanation:
A rock is a hard/solid material. Rocks are separated into different groups based off the minerals they have in them, the groups are metamorphic, igneous, and sedimentary. Rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.
hope this helps!
