How does one man make every sperm different?
Sperm are all different (just like eggs) because they contain all of his genetic history. Each sperm and each egg contain the ability to make a unique person, otherwise siblings would all look exactly alike.
What carries genes from parents to offspring?
Genes are carried from parents to offspring through the reproductive cells, such as sperm and egg cells. These cells contain the genetic information that is passed on to the next generation during the process of fertilization.
Can a girl get pregnant through her genes if sperm gets on her crotch?
What are you trying to say by "through her genes"? Did you mean "jean"? If sperms get into her virgina, then yes. If just outside, on the surface, then no. Very unlikely!
Why are sex linked genes inherited differently than non sex linked genes?
In human cells, each cell nucleus contains pairs of chromosomes where one half of the pair is inherited from the mother (in the egg) and the other half inherited from the father (in the sperm).Sperm and eggs are produced by a special cell division process called 'meiosis' which tears the chromosome pair in the parent's cell nucleus into 2 halves, each half going into a separate sperm or egg.The sex chromosomes in humans (and may other but not allorganisms) are labeled:-'X' and 'Y'. Male cells contain the pair 'XY' and Female cell contain the pair 'XX'Thus when males produce sperm and the chromosome pair is torn in half, 50% end up with the 'Y' half and and 50% with the 'X' half.If a 'Y' sperm fertilizes the egg the offspring will be male, if the 'X' sperm fertilizes the egg the offspring will be female.Thus as the sex related genes are found along the length of the sex chromosomes, in males the genes that inherited on the Y chromosome are different from those in females. The key is that the sex linked genes are located on DIFFERENT chromosomes.
Do all body cells activate the same genes?
All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.
What does a male sperm contain?
It contains half your genes
How many genes does zygote contain?
A zygote contains a full set of genes, which typically includes about 20,000 to 25,000 genes in humans. These genes come from the genetic material contributed by the sperm and egg during fertilization.
How does one man make every sperm different?
Sperm are all different (just like eggs) because they contain all of his genetic history. Each sperm and each egg contain the ability to make a unique person, otherwise siblings would all look exactly alike.
How many genetically different types of sperm cells will result with genes A and B on one chromosome and a and b on the homologous chromosome?
There will be four different genetically different types of sperm cells as a result of the combination of genes A and B on one chromosome and a and b on the homologous chromosome: AB, Ab, aB, and ab.
when sperm donating, do they look for genes like being tall or handsome looking ?
No, they do not check genes of those nature when donating sperm.
What carries genes tha determine whether a person is a male or female sperm?
The answer is sperm
Do energy contain bull sperm?
None, energy drinks do not contain bull sperm.
Is cytoplasm in sperm?
No. Cytoplasm is the fluid within a cell. Therefore, sperm does contain cytoplasm, but cytoplasm cannot contain sperm.
Is the egg the only one who contains genetic material?
No, genetic material is also contained in the sperm cell. During fertilization, the genetic material from the egg combines with the genetic material from the sperm to create a unique set of genes for the offspring.
What contains genes from both parents?
ovam and sperm
What is a sperm cell main function?
sperm main function is to carry the male genes to the egg
Are sperm and egg cells in humans Have either all dominant or all recessive versions of genes?
The sperm and egg sex cells (or gametes) have both recessive and dominant genes in them.
