An adult cell is "diploid", it has 2 sets of each chromosome.
To make a sex cell these chromosomes pairs are split in two (during mitosis) and one half of each pair goes into each gamete (the sperm in a man or an egg/ovum in a woman) which is "haploid". The "haploid" gametes therefore contain half the number of chromosomes as compared to an adult call.
When a man an a woman have sex the gametes from each meet and fuse together, giving the zygote produced 2 sets of each chromosome - back to the "diploid" state. The zygote then grows into the new baby which contains half the generic code form the mother and half the genetic code form the father - a wonderful new mix.

Are most animal gametes diploid or haploid?
Gametes are haploid, meaning they contain half the genetic material of normal (somatic) cells. This is so that when the two different gametes fuse (during sexual reproduction), the resulting organism will once again have the correct amount of chromosomes - half from each gamete.
How many single chromosomes are in a human gamete?
A human gamete contains 23 single chromosomes. Gametes are haploid cells, meaning they have half the number of chromosomes compared to diploid somatic cells, which contain 46 chromosomes. Each gamete, whether sperm or egg, carries one set of chromosomes, which is crucial for sexual reproduction. When two gametes fuse during fertilization, they restore the diploid number of chromosomes in the resulting zygote.
What is the ploidy of the cells of the tetrad of the pollen plant?
The cells of the tetrad in a pollen plant are haploid, meaning they contain a single set of chromosomes. This haploid condition is important for sexual reproduction, as it ensures the resulting gametes have the correct number of chromosomes when they combine during fertilization.
What chromosomes are found in body cells but not sex cells?
Sex cells (better known as gametes) being product of meiosis have single set (haploid number) of chromosomes whereas body cells have diploid number. Thus, 22 pairs of autosomes and one pair of sex chromosomes (XY), thus 46 chromosomes are present in our body cells. The gametes (sex cells) contain only 23 chromosomes in each.
What is laploid?
A haploid is a cell or organism that contains a single set of chromosomes, represented as n. In humans, for example, haploid cells are the gametes (sperm and eggs), which each contain 23 chromosomes. This contrasts with diploid cells, which have two sets of chromosomes (2n), one inherited from each parent. Haploidy is crucial for sexual reproduction, as it ensures that when gametes fuse during fertilization, the resulting zygote has the correct diploid chromosome number.
How many single chromosomes do humans have in their bodies?
Human cells contain forty-six chromosomes each. An exception to this is gametes (oocytes and sperm), which contain twenty-three chromosomes each.
Are most animal gametes diploid or haploid?
Gametes are haploid, meaning they contain half the genetic material of normal (somatic) cells. This is so that when the two different gametes fuse (during sexual reproduction), the resulting organism will once again have the correct amount of chromosomes - half from each gamete.
How many pairs of chromosomes found in a gametes?
In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.
What term is used to describe the single set of 23 chromosomes contained in the gametes?
23 pairs of chromosomes is called the diploid number.--- DNAJamiana:Genotypewhich one dang it don't put two of these answers in this

How do the number of chromosomes compare in gametes and somatic cells?
I will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.
How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.
What does the term haploid mean?
The haploid number (n) is the number of chromosomes in a gamete of an individual. This is distinct from the monoploid number (x), which is the number of unique chromosomes in a single complete set. Gametes (sperm, and ova) are haploid cells. The haploid gametes produced by (most) diploid organisms are monoploid, and these can combine to form a diploid zygote. For example, most animals are diploid and produce monoploid gametes.
Which cell contains only a single set of chromosomes?
A single complete set of chromosomes is called a haploid set of chromosomes. It is generally represented by the letter N. In humans for example, there are a total of 46 chromosomes per somatic cell. Since there are two copies of each chromosome. the 2N number for human is 46 and N = 23.
