Answer:

True

Explanation:

Cell cycle checkpoints are an important layer of control of the cell cycle. The cell cycle is a process by which cells divide.

There are 4 stages of the cell cycle G1, G2, S and M.

When the cell goes through the cell cycle, each stage has different processes that must occur for the cell to properly divide. During G1, the cell must grow to sufficient size and the environment must be favorable for cell division. During S phase, all the DNA must be properly replicated. during G2 the cell must prepare for division. During M, the cell actually divides.

There are 3 checkpoints throughout the cell cycle. The G1 checkpoint ensures the cell has reached sufficient size. The G2 checkpoint ensures the DNA has been properly replicated. The M checkpoint makes sure the chromosomes are properly attached to the spindles to split the DNA between 2 new cells.

Without these checkpoints, the cell can divide uncontrollably which can lead to cancer.

Which statement about inheritance is true? Girls get most of their traits from their moms; boys get most of their traits from th
notka56 [123]

Answer:

The correct answer is the third statement.

Explanation:

In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.  

When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
