WebChromosomes are arranged in pairs as one is inherited from one parent and the other is inherited from the other biological parent. Karyotype: The ultimate chromosome complex inside the nucleus is called the karyotype. This karyotype is a laboratory imaging technique that is used to identify any defective or abnormal portion in the chromosome.
