Q. How does the number of chromosomes found in the two new daughter cells compare to the number of chromosomes found in the mother cell?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Q. How does the number of chromosomes in the two new cells compare with the number in the original cell?
How does the number of chromosomes in the two new cells compare with the number in the original cell and at the end of cell division? The number of chromosomes in each of the two cells equals the number in the original cell.

Q. How does mitosis maintain the chromosome number in each generation of the cell cycle?
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells.
Q. What has happened to the chromosome number?
A change in the number of chromosomes can cause problems with growth, development, and function of the body’s systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.
Q. How did Noonan syndrome get its name?
Pediatrician John Opitz proposed the eponym Noonan syndrome, which was adopted in recognition of dr. Noonan, as she was the first to indicate that this condition occurs in both sexes, is familial in certain cases, includes congenital heart defects and is associated with normal chromosomes.
Q. What is Noonan syndrome life expectancy?
Life expectancy with Noonan syndrome is generally normal, but there may be health problems that need to be addressed with medical or surgical attention. Bleeding can result in blood loss, which can cause symptoms of fatigue.
