crossing over during meiosis is important in that it allows the occurrence of various genes, this is it promotes the increase of different genes. lets remember that meiosis occurs in sexually producing animals and that the first phase of meiosis is the reduction of the haploid number to the diploid number. this reduces the occurrences of increasing numbers in chromosomes. crossing over takes place during pro-phase
What else can I help you with?
Why meiosis gives 4 different gametes?
Because of the crossingover and independant assortment happens in metaphase1.
What does the chromosome number do during meiosis?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
When a child has Trisomy when does the mutation occur?
during meiosis
Why are there two sets of phases during meiosis but only one during meiosis?
burr
What stage of of meiosis do homologous pairs separate?

How genatic material can be rearnged during meiosis?
By crossingover.
Why meiosis gives 4 different gametes?

If a child is born with down syndrome when did the mutation occur?
During meiosis
What does the chromosome number do during meiosis?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
Why is meiosis important?
Meiosis is important for many reasons. For example, during sexual reproduction, meiosis is important to allow the child the same number of genes as their parents. Meiosis is also important for the reproduction of the 4 haploid cells.
When a child has Trisomy when does the mutation occur?
during meiosis
Why are there two sets of phases during meiosis but only one during meiosis?
burr
When are four haploid cells formed?
in meiosis, or after the cell has split two times
What stage of of meiosis do homologous pairs separate?
Reduction Division
How many daughter cell are produced when chromosomes undergo meiosis?
A total of four daughter cells are created during meiosis. There are two phases of meiosis, meiosis 1 and meiosis 2. During meiosis 1 two daughter cells are created while during meiosis 2 four daughter cells are created.
What reproduction is meiosis an important step for?
Meiosis is important for the production of gametes (sperm and eggs) in humans.
Are the chromosome copied before meiosis or during meiosis?
before
