To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl. To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl.
Two eggs are needed. Both eggs are individually fertilized by two different sperm. But the reason they are not identical is because the egg does not split in half, thus splitting the DNA inside the egg into two eggs like in a normal production of identical twins.
Identical twins are when a single egg and a single sperm combine to form a zygote and then the zygote splits into two separate embryos.
Fraternal twins are formed when two separate eggs are fertilized by two separate sperm.
Between one and three, depending on how many are identical and how many fraternal.
Two.
The gametes (sex cells): sperm and egg.
Interphase is the phase where cell division doesn't happen. For a zygote to occur, two gametes need to be combined. These gametes are created through meiosis, and then combined through sexual reproduction.
The gametes are the sex organs in sexual reproduction. The female gametes are known as eggs or ova and the male gametes are known as sperm. The gametes carry the genetic information need to form a fertilised egg. When the sperm fuses with the egg they form an ovum which develops into a foetus.
they are always the same gender
Yes Edited answer: No, only crptogames need water for fertilization. In higher plants like angiosperms, the gametes are non-motile and male gametes reach near the egg for fertilization with the help of pollen tube.
They have the same gametes as any other animal. Egg and sperm. Gametes are reproductive cells. All animals need this to survive and not go extinct.
Gametes require half the number of chromosomes of a somatic (regular) cell as gametes are the sex cells. When gametes combine to make a zygote (a fertilised cell), the complete number of chromosomes will be present.
Gametes are involved in sexual reproduction. In order for the resulting cell from two gametes merging to have the correct number and arrangement of chromosomes, the gametes themselves need to each have exactly half of the chromosomes. If this fraction varied in any way, extreme defects would occur due to the highly different genes the resulting cell would have.
Gametes are haploid cells which means they have only half the normal number of somatic cell (diploid). Somatic cells have 46 chromasomes, organised into 23 pairs, and gametes have only one chromasome from each pair.
Just one. If you have two egg cells, you may have twins.
reproduction are of 2 types sexual reproduction which involves gametes male gametes:-- sperms female gametes:-- ovum these 2 gametes need to be fused together to form an embryo then through mitosis it will divide millions of time to make a baby in plants male gametes:-- pollen grain female gametes:-- ovary in these when pollen gets in another flower due to pollination it forms an pollen tube through the style and fuses with the ovary and forms seeds!! in short the gametes are responsible for reproduction in sexual reproduction
You can breast fed twins. Many twin mums do it successfully. You can feed one at a time or together and there are special feeding cushions that you can purchase to assist. Alternatively you can use your own pillows. Many mothers will feed twins in bed. You may need some assistance with positioning the babies.
i think you mean conjoined twins. These specials twins are joined together sideways when they were born, and it will need a surgery to get them apart.
you need to keep trying, the game will chose twins automatically.

You dont need any thing other then a women and man, haveing twins is a random thing. Essentially, the above answer is correct. However you can increase your chances of conceiving twins through certain fertility treatments.
The water carries the gametes(sperm) to the other mosses for pollination.
