According to http://biology.clc.uc.edu/Courses/bio104/meiosis.htm,"Somaticcells have two sets of chromosomes; one set from eachparent. For example, in humans one set = 23 chromosomes, soour somatic cells have 46 chromosomesarranged in 23 pairs. The two chromosomes in each pair are referredto as being homologouschromosomes, so we could say that humans have 23 pairsof homologous chromosomes. The two chromosomes of each pair carrygenes for the same trait (for example, eye color) at the samelocation, but not necessarily the same form of that gene (forexample, brown vs. blue eyes).An important exception to this is thesex chromosomes, the X and Y chromosomes.Although these chromosomes pair with each other, they are not thesame size. The X-chromosome is longer and has genes for many traitswith no match on the Y-chromosome. A person with XX would be femaleand someone with XY would be male (although, that’s not trueof all other organisms). All the other chromosomes are calledautosomes." Further, "Somatic cells havetwo sets of autosomes (however many pairs that is) and one pair ofsex chromosomes so are called diploid or2n cells. Thus, humans would have 44 + XX or 44 +XY chromosomes, and fruit flies would have 6 + XX or 6 + XY.Gametes orsex cells (eggs from female and sperm from male) have onechromosome from each autosome pair and one sex chromosome (one setof chromosomes), thus are called haploid or1n. Human eggs would have 22 + X chromosomes, andhuman sperm would have 22 + X or 22 + Y chromosomes. Similarly,fruit fly eggs would have 4 + X chromsomes and their sperm wouldhave 3 + X or 3 + Y chromosomes." So far as sex cells beingthe same, Wikipedia says, "Genetic recombinationis the process by which a strand of genetic material (usuallyDNA; but can also be RNA) is broken and then joined to adifferent DNA molecule. In eukaryotes recombinationcommonly occurs during meiosis as chromosomal crossoverbetween paired chromosomes. This process leads tooffspring having different combinations of genes fromtheir parents and can produce new chimeric alleles"(alleles are alternative versions of genes) And, according toHowStuffWorks.com, "Each cell in your bodycontains a set of chromosomesfrom your mother (her egg) and your father (his sperm). When youlook at human chromosomes, they are X-shaped, except for the male Ychromosome. When your body produces sex cells (sperm or egg,depending on whether you are a male or female), your body mustreduce the number of chromosomes by half to go into the sex cells.To do this, it randomly sorts chromosomesfrom both sets in one cell division and then reduces them by halfin another. Therefore, each sperm or egg that your bodyproduces is unique and different -- it contains a different mix ofyour mother's and father's genes. This is why twobrothers in the same family can look and act totally different fromone another even though they come from the same parents -- it alldepends on which genes (chromosomes) were randomly chosen whenproducing the sex cells of the mother and father. I hope thishelps!
