If two Bb guinea pigs cross, there are four possible outcomes:
- both pass the B: the son is BB
- one of the pass the B and the other pass the b: the son is Bb
- both pass the b: the son is bb
Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.
So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.
Answer:
The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.
I think the answer is B
Beacuse It follows the successful completion of S phase, during which the cell's DNA is replicated. Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood, the food molecules, including fat molecules, are routed to every cell in the animal's body.
For the answer to the question above, <span>A
sandwich made with bread and lean turkey is ideal and good because the
carbohydrate/protein mixed together enhances the muscle-building effect of his weightlifting and running activity. This is a food that is good for this kind of workout</span>
