 <quiz display=shuffle>
-{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:
+|type="()"}
+- capacitation of the sperm
+- transport of the sperm through the female genital tract
+- transport of the zygote to the uterine cavity
++ separation of the sperm from semen
+- bidirectional movements of gametes in the uterine tube
+|| Separation of the sperm from semen is not essential for successful fertilization to occur. All the other listed options are essential for successful fertilization.
-{In meiosis, the composition of chromatid is changed during:
+{Fertilization commences when a spermatozoon makes contact with an oocyte and ends:
 |type="()"}
-+ prophase I
++ with the intermingling of maternal and paternal chromosomes at metaphase of the first cleavage division
-- metaphase I
+- when the spermatozoon is completely taken into the ootid
-- anaphase I
+- when the spermatozoa penetrates the zona pellucida
-- anaphase II
+- with the formation of the second polar body
-- prophase II
+- all of the above
-|| During {{Prophase I}} of {{meiosis}} random recombination of DNA occurs that leads to the change in composition of chromatid.
+|| Fertilization commences when a spermatozoon makes contact with an oocyte and ends with the intermingling of maternal and paternal chromosomes at metaphase of the first cleavage division.
-{In a dividing cell, the replication of DNA occurs during:
+{Transport of sperm through the cervix is assisted by all of the following except:
 |type="()"}
-+ interphase
++ capacitation of the sperm
-- prophase
+- the time of the female cycle
-- metaphase
+- properties of the cervical mucus
-- anaphase
+- contractile activity of the uterus
-- telophase
+- pH
-|| Dividing cells replicate their DNA during interphase S phase, before any of the M phase stages. ({{mitosis}})
+|| Capacitation of the spermatozoa modifies the glycoprotein coat and seminal proteins, the spermatozoa are already motile before {{capacitation}}, and therefore capacitation does not assist transport of sperm through the cervix. All the other listed options aid cervical transport of sperm.
-{Which of the following would be the most common karyotype for Turner's Syndrome:
+{Select the correct '''options''' below that refer to the maternal contributions to the zygote:
-|type="()"}
+|type="[]"}
-- 44,XX
++ mitochondria
-+ 45,X
++ nucleolus
-- 44,XY
++ one centriole
-- 47,XXY
+- Y chromosome
-- 46,XX
+- polar bodies
-|| Turner's Syndrome (45,X or 45,X0) is a form of {{monosomy}} associated with either a missing or altered second X chromosome.
+|| Y chromosome is a paternal contribution. The polar bodies do not contribute to the zygote, they are extruded and lost after this first cell stage.
