Which type of twin are created when two ova are fertilized by two sperms?
dizygotic or non-identical twins
How are sperm cells and ova different?
A woman is born with so many ova, or eggs, at the time of her birth. She does not produce any more eggs through her lifetime but instead, looses one or more each month through menstruation A woman cannot use them after menopause. The supply of sperm is endless. A man produces more sperm as necessary and can produce them until he dies.
what cells of a human are diploid and which are haploid?
Exept sperms and ova all are diploid.
A typical human autosome is diploid?
Yes. Only the sperms and the ova are haploid.
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
In what ways are sperm and ova similar?
both ova and sperms are reproductive cells or gametes. they both are haploid because their chromosome number is 1n . they both fuse to form zygote which is diploid and has 2n chromosome number
How do the products of meiosis in men compared to meiosis in women?
the products of meiosis i. e. sperms, in men are several times more than the ova, in women
When does human begins its life?
The life of an human begins when the sex cells or gametes unite.Sex cells are the male sperms and the female ova.During copulation the sperms travels to meet the ova in order to fertilise with it.When they fertilise a zygote is formed which is single cell.
How many ova are in one ejaculation?
None. Ova are female gametes.
Does human penis has one hole for sperms and urine or two?
It all depends on if you have a prince albert or not.
Asexual reproduction of many bryophytes occur through fragmentation gemmae production archegonial or receptacles?
in bryophytes,the spore producing asexual generation alternates with the gamete producing sexual generation.an example is riccia. all bryophytes are gametophytes (gametes are produced) bryophytes have sex organs-antheridium-producing sperms and archegonium-producing ova. they develop on the plant itself when the plant is mature. sperms are produced.they then fall off from the thallus and be on the ground.then fertilization occurs when water is on plant as well as on ground to facilitate the swimming of sperms.when ova in archegonium is mature the top portion of it opens and sperms come inside.only one sperm fuses wit the ova and produces zygote. it develops an outer wall to disable other sperms coming inside.the zygote undergoes repeated divisions and results in the formation of 4 spores. when suitable conditions come, the spores germinate.as they grow the root-like structures develop and the gametophyte is formed.
What is the role of sperms?
The role of sperm is to donate the half genetic material to make a complete diploid individual. It has a tail which help it to swim or to reach to the ova- the female cell. In the head portion there are certain enzymes which can digest the membrane of ova so it can do its job.
