How many sperm cells fertilized the egg cells?
one
Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
How many sperm can be fertilized an ovum?
The exact number of egg cells that can be fertilized is exactly the same as the number of egg cells that are available. For example, in a salmon, about 7,000,000. In a human, normally one, occasionally two to three, rarely up to five and very, very rarely up to seven. Just because they 'can be' fertilized though does not mean that they 'will be' fertilized!
How many cells does a egg have?
An egg has one cell. The nucleus inside the yoke is considered a cell.
How many sperm cells and egg cells are normally needed in order to become fertilized?
One each will theoretically do the job, but normally millions of sperm are required.
How many total sperm cells develop?
Four sperm cells form from a single cell that undergoes meiosis.
How many sperm cells unite with the egg?
One because the sperm is one cell and the egg is one cell
How many chromosomes does the fertilized ovum contain?
The fertilized ovum, or zygote, contains 46 chromosomes. These come from the combination of 23 chromosomes from the egg cell and 23 chromosomes from the sperm cell.
How many spermcells is needed by the eggcell?
An egg cell only needs one sperm cell to be fertilized. Human male ejaculate can contain 200 000 000 sperm.
How many chromosomes do humans have in each of their reproductive cells why is it important?
In both an egg cell and a sperm cell, there are 23 chromosomes. The sperm and egg unite (fertilize) to create a zygote (fertilized egg). A zygote has 46 chromosomes. This is important because if a sperm and/or an egg cell have 1 more or 1 less chromosome, a mutation could form in the zygote.
How many chromsomes does sperm and egg have?
Human sperm and egg cells are called haploid. That means they have half the number of regular body, or diploid, cells. Since normal cells in the human body have 46 chromosomes, sex cells have half that number, or 23 each. When they combine they make a fertilized cell with 46, just like the parents.
How many egg cells are used with twins?
It depends on the type of twins If It was identical (monozygotic) twins, one egg is fertilized (As you can see, identical twins have similarity in phenotype (the observable characteristic of an organism) because of development of one zygote divided into two embryos) but if it was non-identical twins, two eggs or more (such as triplets or quadruplets) are fertilized. The twins have differences in phenotype
