e. Division process occurs twice.
Fill in the blanks (a) Mitosis occurs in our ..... cells. (b) Mitosis produces two daughter cells whereas meiosis produces ...... daughter cells. (c) Meiosis occurs only in ..... cells. (d) Modern humans have 46 chromosomes. Their sperms and eggs will have......chromosomes each. (e) During the pairing of chromosomes in meiosis, the ...... chromosomes come to lie side by side. (f) The.......(s) are surrounded by radiating rays and termed as aster.
Mitosis is the type of cell division where the number of chromosomes is maintained and in meiosis a diploid cell becomes a haploid cell.
Chromosomes are present inside the nucleus of cells. There are ___________ pairs of chromosomes found in human beings. A pair of corresponding chromosomes of the same size and shape is called a __________________ pair. In the pair both parents contribute one chromosome. Haploid cells have only ______________ the chromosomes of diploid cells. If an organism has more than a pair of homologous chromosomes, the organism is said to be ______________________________. E.g.: ____________________________. The number of chromosomes varies from organisms to organisms.
