Multiple genes, for sure! Just think that we have about 20.000 genes in total and only 46 chromosomes (44+ 2 sex chrsomosomes) in somatic cells, and only half of those in germinal (or sex) cells....

Each non-sex cell contains a full set of chromosomes (humans have 46 chromosomes). Reproductive cells (ie sperm and egg) have only half the number of chromosomes (humans have 23).Each chromosome carries multiple genes, some chromosomes have more genes than others.

Meiosis is the technique of manufacturing sex cells. Like usual cells (in mitosis, or the technique of dividing into 2 new daughter cells), first the cellular duplicates its type of genes. Then, it splits into 2. finally, it splits into 2 again. the outcome's 4 sex cells, each and each with 0.5 the replica of genes of the unique cellular. sex cells contain all of a similar genes as somatic ('usual') cells. yet somatic cells contain 2 copies of each gene and sex cells contain in hardship-free words one replica of each gene. it really is because throughout the time of sexual reproduction, 2 sex cells combine. The ensuing zygote could have 2 copies of each gene-- one from the daddy, and one from the mum. desire this helps!

A chromosome is a single large macromolecule of DNA, and is the basic unit of DNA in any nucleated cell. It contains many genes, regulatory elements and other intervening nucleotide sequences.
All chromosomes contain many genes.

Do a google search on "Chromosome structure". There are plenty of sites and it can tell you a lot more than I can. LOL

multiple for sex and somatic
