how many chromosomes would you expect to find in a sperm cell explain?
312681
The number of chromosomes in a sperm cell is 23 and the number of chromosomes in an egg cell is 23. A white blood cell does not undergo meiosis; hence, the number of chromosomes is 46, just like every other human body cells that contain a nucleus.

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.

During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.

Humans have 23 pairs of homologous chromosomes. How many different kinds of sperm cells can a man produce based on different chromosomal arrangements? Again, assume that the members of each pair are not identical. A sperm cell contains 23 chromosomes with two possibilities for each chromosome.

Explanation: Haploid means half of the normal. A normal human cell has 46 chromosomes or 23 pairs of chromosomes. So a sex or germ cell has 23 chromosomes none of them paired.

In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diploid cells.

It is a haploid cell, meaning it has only one copy of each allele (one of each chromosome instead of two). Normal diploid cells have two copies of each chromosome, for a total of 46. Spermatids have half this number, for a total of 23 chromosomes.

The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. 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.

In humans, the male gamete is called sperm, and the female gamete is called an egg. When the gametes join they form a cell called a zygote. Human sperm and eggs contain 23 chromosomes. Human zygotes contain 46 chromosomes.

A horse has 64 chromosomes in a somatic cell. How many chromosomes would you expect to find in a gamete: 128. 64.

Therefore, meiosis results in four haploid genetically unique daughter cells, each with half the DNA of the parent cell (Figure below). In human cells, the parent cell has 46 chromosomes (23 pairs), so the cells produced by meiosis have 23 chromosomes. These cells will become gametes.
615685
In meiosis, a cell containing the diploid number of chromosomes is converted into four cells, each having the haploid number of chromosomes. In human cells undergoing meiosis, for instance, a cell containing 46 chromosomes yields four cells, each with 23 chromosomes.

Each normal embryo contains 46 chromosomes, 23 of which are contributed by the sperm and 23 by the egg. An embryo that contains 46 normal chromosomes is called a euploid embryo .

Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diploid cells.

Normally, the head of a sperm cell contains one copy of each chromosome. In men with macrozoospermia, the sperm cell head contains extra chromosomes, usually four copies of each instead of the usual one. This additional genetic material accounts for the larger head size of the sperm cell.

The egg and sperm cells are an exception--they have only 23 chromosomes each. ... Sperm and eggs end up with the DNA they get through a process called meiosis. When cells normally make new copies of themselves, each of the new cells ends up with 46 chromosomes (at least for humans).
902425
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, "female" reproductive cell and a smaller, "male" one). ... The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.
