HI! Let"s watch at human chromosomes.This is a photomicrograph of stained human being chromosomes from one human body cell. How numerous chromosomes space there?92. No, count again.23. No, try again.These are the damaged pieces of one long chromosome. No, Walther Flemming did think the chromosomes exist together one long piece that broke up duringmitosis, however this is not true.46. That is correct.Human cells normally have 46 chromosomes; this is the diploid number. Chromosomes room usually arranged in a karyotype, where homologs are displayed side through side. This is advantageous for identifying some person disorders. In this karyotype, how countless pairs the chromosomes are there?46. No, shot again.23. The is correct.
