Do homologous pairs of chromosomes carry the same genes?
How many genes are found on each of your chromosomes?
Humans have 46 chromosomes (23 pairs), chromosomes are long strands of genes, and since the chromosomes come in pairs, so do the genes. There are 25,000 genes in the entire human genome, and since the haploid chromosome number is 23, there are about 100's of genes on the shorter chromosomes and approximately thousands on the longer chromsomes.

What term is used to describe pairs of chromosomes having DNA segments or genes for the same trait?
What are the six basic principles of genetics?
six basic principles of genetics are.... Traits, or characteristics, are passed on from one generation of organisms to the next generation The traits of an organism are controlled by genes Organisms inherit genes in pairs, one gene from each parent Some genes are dominant, whereas other genes are recessive Dominant genes hide recessive genes when both are inherited by an organism Some genes are neither dominant nor recessive. These genes show incomplete dominance source: i got this from my textbook.....and im in 7th grade. the txtbook is called Prentice Hall Exploring Life Science
Asked in Genetics
Which organism has the most genes?
Daphnia, the water flea, was recently discovered to have the most genes of any animal. Although it's genome is only about 200 million base pairs in length, 31,000 genes are contained within it. Compare this to the human genome, which is over 3 billion base pairs long, but contains about 23,000 genes.
