chromosomes and Homologous

Post by faith1726 » Sat Mar 31, 2007 2:35 am

If an organism has 12 chromosomes, how many homologous pairs will it have?

Is the answer 24?


Thank u

I hope I'm not misleading you, but usually when people talk about the number of chromosomes they actually mean the number of pairs of chromosomes. So to say an organism has 12 chromosomes probably means it has 12 homologous pairs of chromosomes, or 24 individual ones.

Usually, the "number" of chromosomes is the total number. The number of pairs (ignoring nonmatched pairs) would be half that, not double.

For example, humans have 46 chromosomes, and 23 homologous pairs of chromosomes.
