When a sperm containing a haploid set of chromosomes 23 and an egg with a haploid set 23 join at fertilization, the resulting zygote will have a diploid set of chromosomes A liver cell in a human female would contain 22 pairs of autosomes and a pair of sex chromosomes known as XX. In all the somatic cells of the body 23 pairs of chromosomes are present. They mean 46 chromosomes in total.
Chromosomes are long segments of genes that carry hereditary information. They are composed of DNA and proteins and are located within the nucleus of our cells. Chromosomes determine everything from hair color and eye color to sex. Whether you are a male or female depends on the presence or absence of certain chromosomes. Human cells contain 23 pairs of chromosomes for a total of There are 22 pairs of autosomes non-sex chromosomes and one pair of sex chromosomes.
How many chromosomes does a human sperm cell contain?
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins , bind to and condense the DNA molecule to maintain its integrity. Chromosomes are normally visible under a light microscope only during the metaphase of cell division where all chromosomes are aligned in the center of the cell in their condensed form. The joined copies are now called sister chromatids. During metaphase the X-shaped structure is called a metaphase chromosome, which is highly condensed and thus easiest to distinguish and study.
Asexual reproduction is only possible if the organism carry both male and female parts such as some plants and fungus. Like humans have 46 chromosomes, but in the gametes there are So when the gametes fuse to form a zygote when reproducing they have the 46 that adults have.
