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.

∙ 14y agoTwo 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.

∙ 12y agoIdentical 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.

What cells need to have mutation in order to pass it on to offspring?
The gametes (sex cells): sperm and egg.
What occurs from interphase in the parent cell to the formation of the zygote?
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.
What is the purpose of gametes in the sexual production?
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.
Do twins need to be in the same sac to be identical?
they are always the same gender
Do angiosperms require water for fertilization?
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.
What type of gametes does a rabbit have?
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.
Why do gametes need 12 the number of chromosomes of a regular body cell?
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.
Why it is important for gametes to have half as many chromosomes as normal body cells?
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.
How many chromosome' s do people have in their gametes?
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.
How many egg cells need to be pregnant?
Just one. If you have two egg cells, you may have twins.
What is responsible for reproduction?
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
How do you breastfeed twins?
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.
What is a stuck twins?
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.
How do you make twins on virtual families?
you need to keep trying, the game will chose twins automatically.
What cells need to have mutation in order to pass it on to offspring?
The gametes (sex cells): sperm and egg.
What do you need to do so that you can have twins?
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.
Why moss plants need water for reproduction?
The water carries the gametes(sperm) to the other mosses for pollination.
