Question:At the beginning of prophase I there are ________ molecules of DNA in a developing human sperm cell.Your Answer:2392CORRECT ANSWER46INCORRECThalf as many (as compared to somatic cell)twice as many (as compared to mature sperm)
During spermatogenesis a cell with 2n chromosomes divides to form four sperm cells. How many chromosomes are in each sperm cell?
Each sperm cell will contain n chromosomes, which is half the number of chromosomes in the original cell.
Why many sperm cell's needed to fertilize an egg cell?
Many sperm cells are needed to fertilize an egg cell because only one sperm cell can successfully penetrate the egg cell's protective layer and fuse with its nucleus to form a zygote. Competition among the sperm cells ensures that the strongest and healthiest sperm cell is most likely to successfully fertilize the egg.
How many chromosomes are present in the cell after the S phase of the cell cycle?
After the S phase of the cell cycle, there are 46 chromosomes present in the cell.
If there are 13 pairs of homologous chromosomes in the parental cell how many chromosomes are there in a sperm?
A sperm cell will have 23 chromosomes, half the number found in a somatic cell. So, if there are 13 pairs of homologous chromosomes in the parental cell, there would be 26 chromosomes in the parental cell, but the sperm cell would have 23 individual chromosomes.

How many sperm cell are there in one person?
A sperm is a single cell, so there is one cell per sperm.
How many chromosomes are in a cell that was formed from a sperm and egg cell?
Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.
How many chromosomes pairs are in a sperm Cell?

How many chromosomes are in an egg or a sperm cell?
there are approximately 69 in a sperm cell and approximately chickens in an egg
How many molecules present in unit cell of NaCl crystal?
There are four molecules present in the unit cell of a NaCl crystal. These consist of one Na+ ion and one Cl- ion, forming the basic repeating unit structure of the crystal lattice.
How many chromosomes are seen in the human sperm cell but not in a human blood cell?
The human sperm cell has 23 chromosomes. White blood cells have 46 chromosomes. Mature red blood cells to not contain a nucleus, and therefore has no chromosomes. Platelets are cell fragments and also do not contain nuclei.
How many sperm cells unite with the egg?
One because the sperm is one cell and the egg is one cell
How many chromosomes will the sperm cell have?
23
How many sperm cell unite with an egg cell?
There can be only one.
How does the chromosomes in a nerve cell differ from those in a sperm cell?
The sperm cell is haploid (has half as many chromasomes as the diploid nerve cell)The sperm cell can contain more mutations (depending on the age of the man, this is the basis of anticipation)The sperm cell's chromasome has undergone recombination (I'm assuming you know what that is)
How many chromosomes in human sperm cell?
too many.
