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 are all the organism that are produces?
Semen consists of 2 components: the sperm component and a fluid component. Sperm is produced by the testicles. The fluid component is secreted by the prostate gland, bulbourethral (or Cowper's) glands, and seminal vesicles. The fluid component provides nutrition for the sperm as well as neutralizes the acidic environement of the urethra of the penis and the vagina of the female.
How many chromosomes should each sperm and egg have?
1/2 the number present in the cells if the parents.
How are zygotes produced?
Zygotes are produced when a sperm cell fertilizes an egg cell during sexual reproduction. This process is called fertilization, and it typically occurs in the fallopian tube. The resulting zygote contains a unique combination of genetic material from both parents and is the first stage of development for a new organism.
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
How many daughter cells are produced during mitosis?
Two are produced in Mitosis and 4 in meosis.
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 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 is the name of the 2 human gametes?
The two human gametes are sperm and egg (or ova). Sperm are produced by males in the testes, while eggs are produced by females in the ovaries. When these gametes unite during fertilization, they form a zygote.
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.
What is double headed sperm?
It is sperm that has 2 heads instead of 1 but, don't worry its very common!:)
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'.
Are ther facts about the reproductive system?
1. 500 million sperm are produced and matured each day by a healthy average male 2. after a sperm has penetrated an egg the outer shell of the ovum makes it impossible for any other sperm to penetrate it. 3. the ovum is larger than sperm 4. the life span of a sperm on average is 36 hours 5. the average life span of an ovum is 12 to 24 hours
How do testicles make sperm?
there r two types of cell in the germinal epithelium of a testicle 1.sartoli cell 2.spermatogenic cell this sartoli cell provide nutrition to the growing sperms the spermatogenic cells are the main sperm producers.the process is here - spermatogonia .. primary spermatocyte ... secondary spermatocyte ... spermatid ... sperm this is the main process.further the process go , more the cell shape is changed .the changes occur- 1.nucleus becomes bigger 2.golgi bodies degenerates but acrosome remains on the top of the head of a sperm 3.mitochondria are arranged behind the nucleus 4.the centrioles are arranged behind the mitochondria and form flagella thus a sperm is produced
