Examine the frog models 2-5 which represent the 2-cell, 4-cell,.. morula stages. During cleavage, the large zygote (fertilized egg), a single cell, divides (by mitosis) into two cells (2-cell stage); these two cells divide again yielding four (4-cell stage); these four cells divide again yielding eight (8-cell stage); and so on. After dividing a number of times, the embryo is a solid ball of cells, the morula. Just like in the starfish, a cavity (the blastocoel) then becomes visible in...

When a cell reproduces by mitosis and cytoplasmic division, does its life end? The diploid chromosome number for the body cells of a frog is 26. What would that number be after three generations if meiosis did not occur prior to gamete formation? Explain your answer. Why do you think that sexual reproduction tends to give rise to greater genetic diversity among offspring in fewer generations than asexual reproduction does?
