Answer:
Trisomy 21 would show presence of an extra copy of chromosome 21 in a karyotype
Explanation:
Humans are diploid organisms, having 23 pairs of chromosomes (46 chromosomes in each cell. Trisomy represents a chromosomal disorder, with presence of an additional chromosome (total 47 chromosomes, instead of 46).
Down syndrome is a genetic disorder caused by trisomy of chromosome 21. Karyotype is used to represent appearance and number of chromosomes present in nucleus of a cell.
Thus, in karyotype trisomy 21 there would be an additional copy of chromosome 21. Diagram of karyotype trisomy 21 is attached with answer.
A karyotype is the number and appearance of chromosomes in the nucleus of an eukaryotic cell.
Answer:
The cell bodies of the preganglionic neurons are in the brainstem or spinal cord of the central nervous system (CNS). The cell bodies of the postganglionic neurons are in autonomic ganglia located peripherally. Axon terminal of preganglionic neurons synapse on dendrites and cell bodies of postganglionic neurons.
