The diploid cells come in twenty three pairs of chromosomes. just like twenty three pairs of shoes. Each always has two.
Homologous chromosomes
A diploid cell has two sets of chromosomes in it. A sperm is the male cell that carries chromosome for reproduction. When the sperms meets with the egg the chromosomes come together to make a baby and it has the full genetic makeup.
Yes. A gamete cell is a sex cell that has one set of chromosomes which equal 23. A gamete cell is a haploid cell. A somatic cell is a non-sex cell that has two sets of chromosomes that equal 46. A somatic cell is a diploid cell. For a haploid cell to become a diploid, two haploid cells must join together, which makes 46 chromosomes (23+23=46)p. This can be done through the reproductive process in humans. To create a baby, the egg from the mother and the sperm from the father join together to make a zygote, fertilized egg (baby), with two sets of chromosomes from both parents.
Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.
It has pairs of matching chromosomes (APEX)
Homologous chromosomes in a diploid cell come from male and female parents during fertilization. Pairing of these chromosomes takes place during meiosis to interchange the genetic material to facilitate evolution among those organisms.
Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell. Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID. Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes. Diploid cells have 23 homologous pairs = total of 46 Haploid cells have 23 chromosomes (that are not paired) = total of 23

During meiosis, the homologous chromosomes come together during prophase I. Pairs of homologous chromosomes align during a process called synapsis and form a tetrad (four sister chromatids, two from each pair of homologous chromosomes). During synapsis, crossing over may occur, during which homologous chromosomes exchange genetic material.
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
In a human, 23 chromosomes (formally known as the diploid number) - half the total in an embryo. The other half come from the egg.
Yes. A gamete cell is a sex cell that has one set of chromosomes which equal 23. A gamete cell is a haploid cell. A somatic cell is a non-sex cell that has two sets of chromosomes that equal 46. A somatic cell is a diploid cell. For a haploid cell to become a diploid, two haploid cells must join together, which makes 46 chromosomes (23+23=46)p. This can be done through the reproductive process in humans. To create a baby, the egg from the mother and the sperm from the father join together to make a zygote, fertilized egg (baby), with two sets of chromosomes from both parents.
Haploid and diploid are terms which refer to the number of copies of a chromosome that are found in the genome of an organism. In humans, for example, there are two copies of each (of our 23) chromosomes. Thus, we are diploid. If there is only one copy of a chromosome, this is called haploid. Human sex cells as well as most plant sex cells (sperm/ pollen, ovum/ oval) are haploid. This is how you end up with a complement of chromosomes that is half your father's, half your mother's. Two haploid cells come together to form a diploid cell, and this cell eventually becomes a person. Diploid is a full set of chromosomes inherited from both parents. In humans this would be 46 chromosomes, or 23 pairs in, mostly, somatic cells. Haploid is half this number of chromosomes and is the result of meiosis, where as diploid is the result of normal cellular mitosis (as well as the result of fertilization). In genetic notation haploid is depicted with "n" and diploid "2n"
Diploid cells are cells which contain 2 sets of chromosomes, which will later be divided into two sets of 23 chromosomes for each daughter cell. The total will come up to be 46 chromosomes. The other type of cell is a haploid. A haploid is a sex cell which contains 23 chromosomes. Later when the sperm enters the egg, or the egg meets the sperm the two sets of DNA (One from the sperm, and the other from the egg) will pair up to make another cell with 46 chromosomes. Different animals have different amounts of chromosomes. I have bases this answer on human cells.
