Why do plants need meiosis?
Meiosis occurs in the reproductive cells to form male and female gametes. For sexual reproduction meiosis is essential. Genetic advance is achieved by crossing over in chromosomes during meiosis, hence meiosis helps in evolution of races in plants.Meiosis occurs in the reproductive cells to form male and female gametes.

Is a diploid organism formed in the fertilization or meiosis during sexual reproduction?
Any cell that forms by meiosis (sexual reproduction) is going to be haploid, half the number of chromosomes. Fertilization brings together these two haploid cells that were produced by meiosis and produces on diploid cell, a zygote.
What changes in the chromosomes occur during meiosis?
waht changes in the chromosomes occur during meiosis
Does meiosis occur in sexual or asexual reproduction?
Meiosis isn't reproduction itself but takes place during sexual reproduction. The function of meiosis is to produce haploid gamete cells that way when fertilization occurs the result are two haploid gametes (half the number of chromosomes) coming together. It occurs only during spermatogenesis or oogenesis, mitosis produces normal somatic cells.
How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
What is the purpose of meiosis in animals?
Meiosis in animals is a type of cell division necessary for sexual reproduction. During meiosis, the chromosomes are halved so that during sexual reproduction two halves from two parents can come together and form one cell, genetically combining their different chromosomes.

How meiosis help in generating variations?
Meiosis generates variations due to activities like independent assortment of chromosomes, crossing over and random fertilization that occur during the process. Meiosis occurs during sexual reproduction.

When do the chromosomes become duplicated?
Chromosomes become duplicated during meiosis. This is the process of replicating sex cells, otherwise known as gametes. This is how humans create new sex cells for reproduction.

Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
Meiosis occurs during?
Reproduction.
