what happens when more then one sperm enters into the ZYGOTE?WHY THE COLOUR OF SPERM IS WHITE NOT OF ANOTHER C

It is very very highly rare when more than one sperm enters into the egg. There are several mechanisms to prevent it from occurring. \n\nIf it were to happen, the zygote would have an abnormal chromosome number and most likely would not make it through gestation.\n\nSperm is white because the proteins that make it up reflect all the visible wavelengths back to your eye.

A white fruited parent could be either WW or Ww. A yellow fruited parent must be ww. Since one of the parents is yellow, the correct answer must be either (B) or (C).\n\nIf a WW mated with a ww, then all of the offspring would be Ww, or white. (C) is ruled out, because yellow offspring were produced.\n\nIf a Ww mated with a ww, then half the offspring would be Ww (white), and half would be ww (yellow). That's pretty much what happened -- about half the offspring (37 out of 77) were white and about half (40 out of 77) were yellow.\n\nThe correct answer is (B): Ww and ww.

B. Secondary spermatocytes... spermatids are the product of the meiosis II which under go metamorphosis to become spermatozoa, but they don't go through meiosis again

semen contains lots of vitamin c (Ascorbic acid) and many sperm do die off before they get to the egg. but the females vagina is not full of urine because the urethra opens on the outside not inside the vagina.  i would say that semen is acidic bearing that information in mind

when you have sexual intercourse and the egg is fertilized by the sperm.If anyone asks you didnt get it from me.

The cells from two separate eggs (twins) can combine into one whilst in the mother's womb - thus one child is born but has two dna's instead of one

This is due to dominant and recessive alleles. For example, in the ABO blood groups, the alleles IA and IB are dominant to the allele IO. Therefore if the zygote is heterozygous for IA and IO blood types, the phenotype will be blood group A. This is because IA is dominant to IO.\n\nThe same principals can be applied to diseases like cystic fibrosis and sickle cell anaemia.\n\nThe heterozygous parent is not affected because the phenotype will be the dominant gene instead of the recessive one. So if two heterozygous parents mate, then there is a chance that the offspring will be homozygous for the condition and therefore the phenotype expressed will be of the recessive genes.

You have normal vaginal secretions.  When you see white substances, this is probably cervical fluid.  Cerival fluid helps sperm reach the egg more easily (the vagina and cervix are very acidic and normally kill sperm quickly. . . cervical fluid helps sperm move faster and minimizes the acidicy).  You should notice a cyclic nature to your secretions.  Starting out with your period, then fairly watery for a few days, then sticky for a few days, then a day or two when the fluid seems like egg whites, then back to water until your period comes again.  If this is what you are experiencing (or something similar to this) then everything is normal.  If you have secretions that are chunky (like cottage cheese) or smell foul (like fish), then you should see a doctor as you likely have an infection of some sort.

Sperm can get into the fallopian tubes within 5 minutes after ejaculation, but it can take up to an hour. But the first sperm usually cannot fertilize the egg. It takes sperm many hours inside the cervix, uterus, or fallopian tubes before it's ready to fertilize the egg, this is called capacitation. During capacitation, the outside of the sperm is prepared for entry into the egg.

Consistency of semen isn't very consistent; you've probably noticed that the thickness of your ejaculate can vary from day to day. This is because the quality of the fluid is very susceptible to a number of factors. Diet, exercise and frequency of sex can all dictate how thick or watery your emissions are, as can the tightness of the clothes that you wear (tight clothing will increase body temperature and can thus impact sperm motility. \n\n\nFor men of normal fertility, sperm creation is a constant, ongoing process. Millions of sperm cells are created each day in the testes; they mature in one to 3 months, after which they're ready to be ejaculated. So, since there are always sperm cells being made, there is a lot of overlap between your "loads." Once one has been released, another should not be far behind.\nActual semen quantity differs among individuals and can also change for the same individual during different times of his life. Genetics plays an important part in how much a male will ejaculate. Most males ejaculate about one teaspoon of semen. Some medications may affect the amount of semen produced. And you will notice that the longer you take between orgasms the larger the quantity of semen you will ejaculate. (You've probably noticed that if you masturbate more than once a day that the second, third or fourth time you achieve orgasm you release smaller and smaller quanitities of semen. Wait overnight and see how much more your body made while you were asleep.) Additionally, the more aroused you get and the longer you take to ejaculate, the more semen your body will produce. Foreplay — touching yourself in special ways in special places — will sometimes stimulate the body to produce more semen, since the body's reproductive glands (such as the prostate) work harder when you're aroused.\nSemen appearance and texture can change naturally over the course of months, days, or even from one ejaculation to another, due to a variety of factors inculding diet.\nSemen from a mature male is usually a milky or pearly-white color. It is not uncommon to see a yellowish tint to the semen if you've abstained from ejaculation for a while. Semen colored with red streaks may signify blood. If you occasionally see a bit of blood it's not necessarily a cause for alarm, but if you see a lot of it, or if it persists, the condition should be brought to the attention of your physician. The same goes any other drastic color changes, which may indicate infection. \nA lot of factors go into the appearance and consistency of semen, including diet, ejaculation frequency, etc., so changing any of these can alter the way your semen looks. Also, it's easy to think that semen is simply sperm cells in water, but it's a much more complex substance than that. So it may have been the absence or presence of something other than actual sperm cells — such as sugars or proteins — that caused your semen to look different before.\nA nocturnal ejaculation may have more prostatic fluid in it (which is whiter and thicker), while a daytime ejaculation may have more sperm and fluid from the seminal vesicles, which tends to be more clear and less viscous.

I think sex has something to do with it...but I'm not sure.\n\nbut after that, 2 eggs 2 sperms individually...duh

The development of twins.\n\nA single ovum is released from the ovary.\n\nThe ovum is fertilised by one sperm.\n\nThe zygote divides to form an embryo.\n\nThe embryo splits into two identical embryos.\n\nEach embryo completes its development.\n\nSo, twins are identical because they each contain copies of the same set of genes.

When the egg and the sperm fuse (in sexual reproduction) a single cell is formed.  That cell divides and divides and keeps on dividing until a full sized critter or plant is formed.\n\nSingle celled creatures reproduce by splitting in half to make two new critters.

it a that time of ur menstrual cycle when the discharged ovary is thrown out of your body....\nthis egg doesnt gets fertilized due to which it dies after comin in the fallopeon tube of the female vagina .\nonce the sperms enter the vagina when the egg is on the wall of fallopeon tube it gets fertilized and a baby is born....\nthis discharge is along with blood ...

No, Only the count of sperm in his (life fluid) goes low and the sperm's activity becomes slower, and if he stops for as less as a week or two the count goes higher again and he is ready to have babies again,

Unfertilized ova as well as sperm are haploid, meaning they contain only one set of chromosomes. These are the only cells in the organism which have only half the number of chromosomes. We can say that haploid is "n". Diploid cells contain both sets from the mother and father, so it is "2n".\n\nThe zygote is basically an embryo which is the by-product of a fertilized ovum. It therefore has 14 chromosomes from the mother and 14 from the father, so 28 total. This assumes that all goes well. Sometimes there are chromosomal abnormalities but in the vast majority of cases the zygote has twice the number as the unfertilized ovum ("egg") as well as the sperm.
