Ex: Homo sapiens 2n=46, Pisum sativum 2n=14, Phaseolus vulgaris 2n=14, Allium cepa 2n=16, Ascaris megalocephala univalens 2n=2.
Polyploid indicates the number of haploid sets; any thing more than two, like Triploid (3n), Tetraploid (4n) etc.
Human chromosome karyotype; look at the secondary constriction on chromosomes13,14,15,21 and 22; Chromosome 2 is believed to be originated from chimpanzee chromosomes 2A and 2B; Analysis further showed 7600 genes shared between two genomes; certain Genes found as forkhead-box P2 transcription factor which is involved in human speech acquisition and hearing ability.
If there are any changes from the normal diploid number, like loss or addition of one or two chromosomes leads to Aneuploidy.
The haploid consists of one set of chromosomes, where every chromosome is unique in its structure, morphology and genetic content and form one set of chromosomes.
The diploid consists of two such haploid sets of chromosomes.
The Bing Network is a part of your customers' lives, powering the devices, apps and sites they use every day and meeting them in the moments that matter most.They are localized in nucleus in higher organisms, but suspended in bacteria as DNA protein threads.In viruses the genetic material can be RNA or DNA are compacted in proteinaceous capsids.Specifically, the fusion site sequence binds to at least 11 different transcription factors, including RNA polymerase II, the key enzyme that transcribes genes.Transcription factors are specialized proteins that turn genes off and on.
