ok so i know that a homolgous chromosomes are the two chromosomes composing a pair have same length, centrosome position, and stain pattern. but sometimes ...Homolgous chromosomes can also be non-identical chromosomes that contain information for the same biological features and contain the same genes at the same loci but possibly different genetic information
...right????
k so i am confused ....it says we inherit i chromosome from each parent ( chromosome is basicaly 1/2 of X what i mean is a line : / )
so on the karyotype it has 22 pairs of homolgoues chromosomes = 46 homolgoues chromosomes?
= 46 x 2 = 92 chromosomes right?
so then that dvided by 2 is 46 chromosomes ....so then why do they say 23 chromosmes from each parent?
shouldn't it be 23 homolgouse pairs / pairs /duplicated chromosomes?
very confused because in one chapter it says the X = duplicated chromosomes and / is a chromosome ( sorry the closest thing to a isual)
on the other chapter it sems like a chromosome = X

You get one from each pair of homologous chromosomes, so that is 23. There are 22 pairs, plus the X/Y chromosome in men and XX in women, making the 23rd pair.

yes there are 22 pair of chromosomes and the 23rd pair are the sex chromosomes so all in all, there are 23 pairs of chromosomes.
