You have 10 minutes to finish the quiz.
Q.1 :
Which statement about haploid and diploid stages is false
ferns exhibit haploid and diploid stages in their life cycles
a spore develops into haploid adult plant
the zygote gives rise to haploid adult plant
in the diplod stage of a plant, only the gametes are haploid
Q.2 :
During meiosis
A: gametes are formed that are diploid
B: gametes are formed from diploid sex cells
C: gametes are formed that are haploid
B and C
Q.3 :
Which of the following occurs during meiosis but not during mitosis?
Chromosomes align at the metaphase plate
Chromatin condenses into chromosomes
Chromosomes migrate to opposite poles
crossing over
all of the above occur during mitosis and meiosis
Q.4 :
What is the function of meiosis?
to make exact copies of the parent cell
to make a cell with twice the number of chromosomes as the parent
to make four cells with the same chromosome number as the parent
to make cells with a haploid number of chromosomes
Q.5:
Humans have 46 chromosomes. That number of (human) chromosomes will be found in
all cells prior to mitosis
all egg and sperm cell
during G1 in somatic cells
during G1 in all cells of the body
gamete producing cells after meiosis II
Q.6 :
Which of the following events occurs during oogenesis but not spermatogenesis?
meiosis
crossing over
unequal cytokinesis
both give rise to four sperm (ovum)
Q.7:
Crossing over
is the exchange of alleles between 2 homologous pairs of chromosomes
takes place during prophase I
produces new alleles on chromosomes
all of the above
Q.8 :
Which statement about the uterine cycle is false?
FSH annd LH promotes maturation of the ovum
FSH and LH stimulate estrogen (estradiol) release form the follicle
follicle turns into a secretory cell
progesterone promotes increased blood flow ito the uterine wall
all are correct
Q.9:
A single human oocyte can produce ? eggs
46
23
4
2
1
Q.10 :
Which statement is
not
correct
human primary spermatocytes (male germ cells) are diploid
human primary oocytes complete meiosis II before ovulation and become fully matured eggs
human primary oocytes are arrested in prophase I until sexual maturity
a human primary spermatocyte develops into 4 gametes (sperm)
