Fertilization Interactive Component

Attempt the Quiz - Fertilization 
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Fertilization from the lecture and practical.

  

1 At fertilisation:

male and female pronuclei complete their meiotic division
male and female pronuclei enter interphase
cyclic AMP (cAMP) is secreted by the zygote to block polyspermy
the zona pellucida is discarded
All of the above.

2 All of the following are essential for successful fertilization except:

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

3 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
when the spermatozoon is completely taken into the ootid
when the spermatozoa penetrates the zona pellucida
with the formation of the second polar body
all of the above

4 Transport of sperm through the cervix is assisted by all of the following except:

capacitation of the sperm
the time of the female cycle
properties of the cervical mucus
contractile activity of the uterus
pH

5 Select the correct options below that refer to the maternal contributions to the zygote:

mitochondria
nucleolus
one centriole
Y chromosome
polar bodies
