how many chromosomes human egg cell?
76591
In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. A human egg is haploid (has 23 chromosomes) and a sperm is haploid (has 23 chromosomes). Upon fertilization, the new baby now has the 'correct' human number of 46 chromosomes in each of its somatic cells.

Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception.
45175
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Along the segments of our DNA, genes are neatly packaged within structures called chromosomes. Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception.

All body cells expect for the reproductive cells. How many chromosomes do human somatic cells contain? 46 chromosomes composed of two sets of 23 chromosomes (2n; diploid).
1393171
In humans, special cells called germ cells undergo meiosis and ultimately give rise to sperm or eggs. Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes).

Because they have only half the total chromosomes in a somatic cell, they are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. A human egg is haploid (has 23 chromosomes) and a sperm is haploid (has 23 chromosomes).
76074
At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis).
989132
Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes.
944705
Human oocytes pack the mother's DNA into 46 chromosomes. When they divide into eggs -- a process called meiosis -- these 46 chromosomes gather along the midline of the oocyte and are pulled in two directions by spindle fibers. The final product of meiosis is an egg cell with 23 chromosomes.

Why your body can not use mitosis to make sperm or eggs Thus, the zygote has 46 chromosomes, and when the zygote undergoes mitosis to begin to form an embryo, each cell will have the normal number of 46 chromosomes.

It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.
1247864
Each cell in a normal human embryo has 23 pairs of homologous chromosomes, for a total of 46 chromosomes per cell.
253677
In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

Normally, meiosis causes each parent to give 23 chromosomes to a pregnancy. When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes. But if meiosis doesn't happen normally, a baby may have an extra chromosome (trisomy), or have a missing chromosome (monosomy).

Humans have 23 pairs of chromosomes. That means that one person could produce 223 different gametes. In addition, when you calculate the possible combinations that emerge from the pairing of an egg and a sperm, the result is (223)2 possible combinations.

The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells. There are 22 pairs of autosomal chromosomes and one pair of sex chromosomes.
