a human diploid cell has two chromosomes.
how many chromosomes does a human diploid cell have?
two
like all cells, somatic cells contain dna arranged in chromosomes. if a somatic cell contains chromosomes arranged in pairs, it is called diploid and the organism is called a diploid organism. (the gametes of diploid organisms contain only single unpaired chromosomes and are called haploid.) each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. for example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. by contrast, gametes of diploid organisms contain only half as many chromosomes. in humans, this is 23 unpaired chromosomes. when two gametes (i.e. a spermatozoon and an ovum) meet during conception, they fuse together, creating a zygote. due to the fusion of the two gametes, a human zygote contains 46 chromosomes (i.e. 23 pairs).

the human diploid cell rabies vaccine (h.d.c.v.) was started in 1967. human diploid cell rabies vaccines are inactivated vaccines made using the attenuated pitman-moore l503 strain of the virus. human diploid cell rabies vaccines have been given to more than 1.5 million people as of 2006.









































in addition to these developments, newer and less expensive purified chicken embryo cell vaccine, and purified vero cell rabies vaccine are now available. the purified vero cell rabies vaccine uses the attenuated wistar strain of the rabies virus, and uses the vero cell line as its host.
