What else can I help you with?
Why are two sperm never identical?
No two sperm cells are identical because of the process of crossing over that occurs in prophase I of meiosis.
Which event can result in the birth of identical twins?
Two egg cells are each fertilized by separate sperm cells.
Do cells are genetically identical?
Cells form new cells with identical genetic composition through mitosis. This essentially involves the cell producing enough resources for two cells and then splitting it's membranes into two separate and distinct bodies.
How can non identical sheep twins form?
Non-identical twins are when 2 sperm cells fertilize two different eggs during the same pregnancy.
Is identical twins are more closely related than tyhe fraternal twins?
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
What sperm is formed during mitosis?
Sperm is not formed during mitosis. Mitosis is a type of cell division that occurs in somatic cells (non-reproductive cells) and produces two genetically identical daughter cells. Sperm formation, known as spermatogenesis, involves meiotic division, which produces four genetically different haploid cells called spermatids that later mature into sperm cells.
What kind of cells does the process mitosis and meiosis make?
Mitosis produces cells that are identical to the original cell, called daughter cells. Meiosis forms cells with half the amount of genetic material, which are used in sexual reproduction to create gametes such as sperm and eggs.
What is the diffence between identical twins and fraternal twins?
Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
What is the number of cells resulting from mitosis?
2 diploid cells
How many identical cells were formed after mitosis?
Mitosis results in two identical daughter cells that are genetically identical to the parent cell. So one parent cell can produce two identical daughter cells after mitosis.
Does mitosis result into two identical daughter cells?
noYes it results two identical cells.They are same as mother cells
How are identical and non-identical twins produced?
When an egg is fertilized by a sperm, it becomes a zygote. That zygote goes through cell division to become an embryo.Sometimes, the zygote splits and becomes two separate organisms - they will be identical twins. If the zygote splits and separates multiple times, you can get triplets or even quadruplets. They will all be (more-or-less) genetically identical.If two eggs are released during ovulation and each one is fertilized (by a separate sperm) then you will have fraternal (non-identical) twins. Again, if multiple eggs are released (for example, when a woman is undergoing fertility treatments) and each one is fertilized by a separate sperm, you can get triplets, quadruplets, etc. They will all be genetically different and can even be different sexes.
