In males, meiosis occurs in precursor cells known as spermatogonia that divide twice to become sperm.

What happens in meosis 1 that does not occur in meosis 2?
Pairing between homologous chromosomes
What is the stages of meosis?
1. photophase 2. metaphase 3. anaphase 4. telophase
What happens in the Telophase II?
Cells produced at the end of telophase 2 (the final stage of meosis 2) become gametes containing haploid number of chromosomes.
How are zygotes produced?
They form from the merger of two haploid (half-gened cells: a sperm and an egg). Actually in mammals the egg swallows the sperm, and the nuclear material fuses together.
How many sets of instructions are there in the nucleus of an egg cell or sperm cell?
1/2
What happens in meosis 1 that does not occur in meosis 2?

1. photophase 2. metaphase 3. anaphase 4. telophase
What is the stages of meosis?

How many daughter cells are produced during mitosis?
Two are produced in Mitosis and 4 in meosis.
What happens in the Telophase II?
Cells produced at the end of telophase 2 (the final stage of meosis 2) become gametes containing haploid number of chromosomes.
What specialized cell are produced in male and female reproductive system?
sperm or an egg. Each contain 1/2 the total DNA of a normal cell. The sperm and egg combine to put these two halves together and create a new DNA combination that is unique to the individual (unless they have an identical sibling/s)
What are not waxes 1 beeswax 2 sperm oil 3 bile acids 4 lanolin?
2.sperm
Is the primary endosperm nucleus haploid or diploid?
I am sure it is (3n).This is because In angiosperms most common type of embryo sac formation, there is fusion of 1 sperm nuclei + 2 polar nuclei=triple fusion resulting in a triploid primary endosperm nuclues.
What are 2 sex cells?
Two types of sex cells are> Sperm (in males)> Egg or ovum (in females)Sperm is produces in the testes.Ovum or egg is produced in the ovaries.Source(s):
What 2 cells made you?
An ovum from my mother and a sperm cell from my father combined to produce a zygote which ultimately produced me.
Why cant mitosis create egg and sperm cells?
Because mitosis creates duplicates of cells with complete copies of the chromosomes in each cell made. For eggs and sperm cells the cell division process has to end up with the eggs and sperm having just 1/2 of the chromosome numbers in each cell made. Eggs and sperm are therefore produced by 'meiosis' and not 'mitosis'.
What is double headed sperm?
It is sperm that has 2 heads instead of 1 but, don't worry its very common!:)
