Question

Describe what “Alternation of Generation” means and describe in detail the human alternation of generation. Make sure to include each of the following terms: haploid, diploid, homologous chromosomes, mitosis, meiosis, somatic cell, germ cell, zygote

Answer 1

The alternation of generation is the life cycle in which distinct haploid and diploid stages are found.

The adult human is diploid ( somatic) in nature because there are found 23 pair of homologous chromosomes are found. The testis and the ovary has germ cells. These cells are somatic or diploid in nature. These cells undergo the process of meiosis and produces gametes. The gametes are haploid in nature because 23 chromosomes are present. The fusion of gametes occurs by the process of fertilisation and produces zygote. The zygote is diploid in nature. The mitotis occurs in zygite in repetitive manber and produces adult. In this way, there is found distinct phase in alternation of generation in human beings.
