-{During Prophase I of meiosis:
+{At fertilisation:
 |type="()"}
-- Reduction of the number of chromosomes occurs
+- male and female pronuclei complete their meiotic division
-+ random recombination of hereditary material (DNA) occurs
++ male and female pronuclei enter interphase
-- already duplicated DNA is separated
+- cyclic AMP (cAMP) is secreted by the zygote to block polyspermy
-- nondisjunction of the chromosomes could occur
+- the zona pellucida is discarded
 - All of the above.
-|| During {{Prophase I}} of {{meiosis}} random recombination of DNA (hereditary material) occurs. There is no reduction in chromosome number, separation of duplicated DNA and nondisjunction of the chromosomes is unlikely to occur during {{Prophase I}}.
+|| The male and female pronuclei enter interphase before commencing the first mitosis.
+{All of the following are essential for successful fertilization except:
-{In meiosis, the composition of chromatid is changed during:
 |type="()"}
-+ prophase I
++ capacitation of the sperm
-- metaphase I
+- transport of the sperm through the female genital tract
-- anaphase I
+- transport of the zygote to the uterine cavity
-- anaphase II
++ separation of the sperm from semen
-- prophase II
+- bidirectional movements of gametes in the uterine tube
-|| During {{Prophase I}} of {{meiosis}} random recombination of DNA occurs that leads to the change in composition of chromatid.
+|| Separation of the sperm from semen is not essential for successful fertilization to occur.
 {In a dividing cell, the replication of DNA occurs during:
