what can a human sperm carrying a y chromosome produce?

The previous answer is incorrect.  It will produce a male offspring if it fertilizes an egg.  Males have a Y chromosone, females have x chromosones.

You can improve your chances. Sperm determine sex. A Y chromosome is lighter than an X chromosome. So, if you ultra-centrifuge sperm, the 'males' will be a higher fraction than the heavier 'females'. \n\nIt's done in animals all the time. It's not 100%, but it sure increases the odds.

In short Meiosis and Fertilisation.\n\nFertilisation brings each haploid gamete cell together, that is, a sperm and an egg. Each of these gametes carries a single copy of each chromosome. It is not until fertilisation that the chromosomes from each parent come together to form the diploid embryo.\n\nBut it's important to note that although we are walking around with 2 copies of our chromosomes, our gametes only have one. This is because the gametes are formed through the process of Meiosis, which halves our DNA. This allows the offspring to have a copy of each chromosome from each parent.

SPERMS ARE THE MALE REPRODUCTIVE CELLS IMPLANTED IN THE FEMALE UTERUS AFTER COPULATION

Not a human male... some aquatic species (and probably others...) have the males carry the baby upon fertalization

First question. If you mean sexual interciurse then of course, IVF (AI) etc\nBut as this is biology then ill assume you mean syngamy between gamets. \nIn which case the option is cloning which is not established as viable in humans yet (Korean research is under fraud investigation so its validity unclear at present) but is not permitted in most countries anyway.\n\nAs to the second question:- NO\nAsides one alleged and unlikely case (the virgin birth of mary yielding jesus christ which if it was true (unlikely) was a dead end as it was a male), parthenogensis (asexual reproduction) has never been reported in humans. Morever it is very unlikely to be viable or to occur due to imprinting etc.

In most instances, human offspring with differing numbers of chromosomes are miscarried before any progression toward birth.  In cases where there are extra chromosomes such as trisomy 21 where there is an extra chromosome on the 21st pair (47 total), the pregnancy may be carried to term and the fetus has a syndrome known as down sydrome.  Kleinfelter syndrome there is an additional X chromosome in males producing XXY.  There are also turners sydrome in females where they are lacking an X chromosome (45), they fail to develop secondary sex characteristics and are also sterile because their sex organs do not mature.  This is only an example of some chromosomal abnormalities.  You can look up more on the web.

anyone can biologically produce/father a child, that is, provide the sperm to create life. but not everyone can take on the parental responsibility to love, nurture, teach, and care for their child. it takes much more of a man to be a dad to his children, than simply procreate.

Genotypes of man and woman : DdPp x DdPp\nPossible gametes of man and woman: DP Dp dP dp X DP Dp dP dp\nChildren: I guess its a dihybrid cross with 9:3:3:1 ratio of phenotypes since you have not mentioned the kind of inheritance.

Chromosomes, either X or Y.

For humans, we need a 1 pair of chromosomes (#1-23).  If we didn't reduce our chromosome, the next generation would carry 2 pairs of chromosomes and that would be incompatible with life.  Our sexual cells (sperm and egg) has 1 set (not a pair of them) of chromosomes so that the set from the egg and the set from for sperm together makes a human with 1 pair of chromosomes.

According to Wikipedia - yes they can. A mutation in the father's sperm can cause it - even if the father does not have it.

Not that I'm aware of. This genetic condition involves the X and Y chromosomes, and not anything else.

I know that the production of testosterone and sperm go hand in hand.  Raise both by taking a zinc supplement.  Be careful with the zinc though, as it can be toxic in high doses.

Not yet, but scientists are working on it. Scientists have successfully grown eggs out of sperm cells in fish (see article). One day it will be possible for gays and lesbians to have biological children.\n\nhttp://www.livescience.com/animalworld/060206_fish_story.html

No, the sperm contains only half of the genetic information that is needed to make a baby, so when the sperm (50%) and the ovum (50%) merge, you get all the genetic information needed to make a baby. Cloning means when the baby's information is not taken from the sperm+ovum, but from another cell in the body (which has 100% of genetic info, like all cells in the body, except the sperm and the ovum). \nBut a human baby has not yet been cloned, only sheep and other animals - it is dangerous to clone because a process called recombination does not occur - that's like mixing. When the sperm and ovum gets together, the DNA gets "mixed" and often the "best" DNA gets selected to give you strong and healthy babies. From a single body cell, the DNA cannot get "mixed" and have to be used the way it is, so the sheep born from this process, for instance, ended up getting all kinds of weird diseases. \n\nPS: the more info part of your question does not make any sense

all normal males are XY.  all normal females are XX.  the female always donates 1 X chromosome to the offspring.  the male donates either an X or a Y to the offspring (50% chance of each event).  If the male donates an X, the offspring will be XX and female.  if the male donates a Y, the offspring will be XY and male.
