It is transplanted routinely to treat a variety of blood and bone marrow diseases, blood cancers, and immune disorders. More recently, stem cells from the blood stream (called peripheral blood stem cells) and umbilical cord stem cells have been used to treat some of the same blood-based diseases
The answer to the first question is a.
Answer:
The daughter cells are genetically identical because mitosis is a process that ensures the equal distribution of the replicated genetic material between these cells
Explanation:
During mitosis, the DNA is duplicated during the interphase (S-phase). Subsequently, the replicated chromosomes are arranged in the center of the parent cell (metaphase) to be finally separated and equally distributed between the daughter cells.
The main benefit of crossing over is that it increases genetic diversity.
<h2>
Crossing over and
Genetic Diversity</h2>
Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells.
The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.
Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment.
In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.
