Question

Identify the wrong statement about meiosis

  1. Pairing of homologous chromosomes. 

  2. Four haploid cells are formed.

  3. Number of chromosomes is reduced to half by the end of meiosis.

  4. 2 cycles of DNA replication occur.

hintHint:

DNA replication is the process by which genomic DNA is copied into cells. Before a cell can divide, it must first copy (or replicate) its entire genome so that each resulting daughter cell has its own complete genome.

The correct answer is:

2 cycles of DNA replication occur.


    • DNA is replicated during the S phase of meiosis.
    • During meiosis, cells pass through this stage only once, and DNA synthesis by replication occurs only once during this stage. Therefore, only one cycle of DNA replication occurs during meiosis.

    Hemophilia disease is produced in the male by how many gene/s?

    • Genetic disorders can be chromosomal, multifactorial and monogenic
    • Hemophilia is a blood disorder that delays blood clotting or hemostasis
    • Blood clotting is a result of cascade of reactions done by clotting factors (1 to 12)
    • Absence of clotting factor VIII or IX causes hemophilia
    • Gene (F8 or F9) responsible for hemophilia is present in X chromosome

    How do genetic disorders happen?

    • Genetic disorder is due to alteration in gene sequence
    • The gene sequence change can occur in a cell irrespective of type of cell division a cell undergoes
    • Mutation can occur at any point of cell division
    • Trisomy can be attributed as a result of meiosis
