geologic time use the layer of Rock to describe relationship of events and their sequence chronological order over the history of Earth the layering is a result of the buildingup tiny beats of rocks sediments or Lava cooling at the surface of many years think think of it like a stock of pancakes-the bottom layer is the one that was placed first and therefore is the oldest. the sediments that create the layer of the earth as said one or top of the other

It could be that he doesn’t specify what kind of vitamins
It is possible if the parents are heterozygous (meaning they have a dominant AND recessive allele for the trait.
Well say the allele for orange is X and the allele for green is X.
Let’s say we have two homozygous orange parents. That means they have no trace of green.
XX
X XX XX As you can see, the Punnett
X. XX XX. Square shows that all offspring will have capital X’s, meaning only homozygous orange offspring is produced. No green babies here.
We can try the same thing with a homozygous parent and a heterozygous parent.
Xx
X XX Xx Here we can see that 50% of
X XX Xx the offspring has a lowercase x. That means they are heterozygous. They carry the green trait, but it doesn’t show because it is masked by the dominant orange allele. So no green babies here either.
Finally we can try heterozygous parents.
Xx
X XX Xx 25% of the offspring is
x Xx xx homozygous for orange. 50% of the offspring is heterozygous for orange. And 25% is homozygous for green. There must be two recessive alleles in order for green to show.
The only way to produce green offspring is to have two heterozygous parents.
