Final answer:
Privet chromosomes differ from human chromosomes in terms of genes and laboratory synapse. Privet cells have different genes, and they cannot synapse with human chromosomes in the lab.
Step-by-step explanation:
The somatic cells of a privet shrub consist of 46 chromosomes, just like human somatic cells. However, there are differences between the chromosomes of privet and humans. In humans, the 46 chromosomes consist of 22 pairs of autosomes and a pair of sex chromosomes. Privet chromosomes do not synapse with human chromosomes in the laboratory, and the genes of privet chromosomes are different from those in humans.
