Explanation / Answer
21. Zygote is formed during the process of fertilization where, 2 haploid cells ( ovum and the sperm cell) combine to form 2n diploid cell.
22. Most of the fungi remain in the haploid state throughout their life span except during sexual reproduction. During reproduction they form diploid cells.
23. Techniques used to visualize the chromosomes in an organism is known as karyotyping. It is a molecular cytogenetic technique to stain chromosome with different colors in an arranged manner.
24. During the process of X-inactivation or lionization, in female mammals, one of the copy of the X chromosome gets inactivated due to its packaging. It become transcriptionally inactive and called as heterochromatin.
