The mammalian corpus luteum produces:
Estrogen
Progesterone
Luteotropic hormone
Luteinizing hormone
The estrus cycle is a characteristic of:
Human males only
Human females only
Mammalian males other than primates
Mammalian females other than primates
At the end of first meiotic division, male germ differentiates into:
Secondary spermatocyte
Primary spermatocyte
Spermatogonium
Spermatid
What is true about cleavage in fertilized egg of human ?
Meroblastic
Starts when egg reaches uterus
Starts in fallopian tube
It is identical to normal mitosis
Ovulation occurs under the influence of:
LH
FSH
Gonads develop from embryonic:
Ectoderm
Endoderm
Mesoderm
Both (b) and (c)
Cells become variable in morphology and function in different regions of the embryo. The process is:
Differentiation
Metamorphosis
Organization
Rearrangement
Blastopore is:
Opening of neural tube
Opening of gastrocoel
Future anterior end of embryo
Found in blastula
During cleavage, what is true about cells?
Nucleocytoplasmic ratio remains unchanged.
Size does not increase.
There is less consumption of oxygen.
The division is like meiosis.
Termination of gastrulation is indicated by:
Obliteration of blastocoel
Obliteration of archenteron
Closure of blastopore
Closure of neural tube
