Half come from your mom's egg and half come from your dad's sperm.
In sexual reproduction, two sexes are used to make the offspring. The "extra" chromosomes come from the sperm.
23 from the father and 23 from the mother
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.
In humans, 46. 23 are passed from each parent to their child.
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
In a human, 23 chromosomes (formally known as the diploid number) - half the total in an embryo. The other half come from the egg.
46 chromosomes (23 pairs) half from the mom half from the dad
There are 46 chromosomes in a human cell, half come from your mother and half come from your father. However a person with down syndrome has 47 chromosomes.
The gametes must have half as many chromosomes as normal body cells because they unite to form a zygote, which is the first body cell of the new organism. For example, human body cells have 46 chromosomes and human gametes (sperm and egg cells) have 23 chromosomes. When the sperm fertilizes the egg, the zygote will have 46 chromosomes, and is the first body cell of the new human.
There are 23 pairs or 46 individual chromosomes in a humans cells. 22 pairs of autosomes and 1 pair of sex chromosomes in normal humans. (There are disorders such as Turners syndrome and Klinefelter syndrome that result in different numbers of chromosomes.)
a human possesses 23 pairs of chromosomes.
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
A gamete will only have one half of the number of chromosomes found in body cells because two gametes have to come together. This means that the two gametes have to have only half of the chromosomes.
The chromosomes in a karyotype are from a sample of body cells.
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.
The human cell has 46 chromosomes. In the sex cell of a human it has one half that many. So 23 chromosomes from each parent. Different species have different number of chromosomes. This is why you do not have mixes such as a centaur.
23, there are 23 chromosomes in human gametes
In humans, 46. 23 are passed from each parent to their child.
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
