Sex is determined by the sperm cell that fertalized it. The egg supplies an X chromosome, and the sperm cell supplieds an X or a Y chromosome. If the result is XX, it is female, if it is XY, it is male.
In humans, the presence of a Y chromosome means the zygote will be male.
So (normal) females will have XX - one X chromosome from each parent.
(Normal) males will have XY - an X chromosome from their mother and a Y from their father.
The sex is determined by the sex chromosomes - one pair out of the total of 23 pairs of chromosomes we inherit from our parents. These come in two versions, called "X" and "Y". In the normal case, I would inherit either two "X" chromosomes, in which case I would be a female, or an "X" and a "Y" chromosome, in which case I would be a male.
The presence of a Y chromosome. XX = female. XY = male.
Right at fertilization.
A gamete is a sex cell: an egg or a sperm. A zygote is a fertilized egg cell.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.
No, a zygote is a diploid because it has the full number of 46 (23pairs) of chromosomes. Two gametes one from the male one from the female meet to form a zygote. gametes = haploid everything else = diploid
SEX CELL is called EGG .It becomes zygote after joined by sperm in fallopian tubes and become foetus and grow at utreus.
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
a zygote is a stem cell
A zygote is diploid, it is formed by the union of a male sex cell (a sperm) and a female sex cell (an ovum) both of which are haploid.
A zygote.
A Zygote is the cell formed when two gamete (or sex cells) are joined by sexual reproduction. The zygote develops into the baby. The zygote is only the initial stage of the development of the offspring. Usually, a zygote if formed by an ovum and sperm. The ovum being the female sex cell and the sperm being the male's.
A gamete is a sex cell: an egg or a sperm. A zygote is a fertilized egg cell.
The Zygote
Sex-liked means liking sex and sex determined is the resolution to have sex.
The sperm and the egg
23
A zygote is developed during fertilization - a process that occurs when two haploid gametes (or sex cells) combine. In more general terms, the zygote is formed when the sperm meets the egg.
A zygote is the initial cell developed through sexual reproduction and formed when two gametes come together. In other words, a zygote results when the female egg is fertilized. After rapid cell division, it eventually becomes an embryo.
