Meiosis Worksheet Answer Key Quizlet Meiosis vs Mitosis Cells are the building blocks of life Whether it is a single cell organism or a multicellular one But to keep life going cells must multiply to heal or reproduce The two main ways of cell division are Mitosis and Meiosis Read below to have a complete idea of the processes of meiosis vs mitosis Mitosis Definition In the cell cycle mitosis is a process in
Meiosis is the process by which sexually reproducing organisms make their sex cells sperm and eggs During meiosis a specialized cell called a germ cell splits to make four new sex cells each with half the number of chromosomes as the original germ cell The prophase I of meiosis occurs in the following stages 1 Leptotene This phase is the start of prophase I It is marked by the condensation of the chromosomes 2 Zygotene In this phase the homologous chromosomes start pairing up called the

For the formation of male gametophyte 1 meiosis and 2 mitoses are required and for the formation of female gametophyte 1 meiosis and 3 mitoses are required One angiosperm seed contains 1 male gametophyte and 1 female gametophyte So to produced 1 angiosperm seed 2 3 5 mitosis will be required Meiosis is the type of cell division by which gamete cells eggs and sperms are produced Meiosis involves two successive nuclear divisions and one cytoplasmic division that produce four haploid cells The first division meiosis is the reductional division during which number of chromosomes is reduced to half
Meiosis is a reduction division because the end result of this special type of cell division is four haploid cells The first meiotic division occurs which results in two cells each with 46 chromosomes Then the second round of meiotic division occurs and each of these two cells divides resulting in four haploid cells After meiosis I DNA content 60 pg is equally divided into two cells i e 30 pg in each cell Both the cells further divide to form four haploid cells during meiosis II so that the DNA content 30 pg per cell is further reduced by half i e 15 pg DNA in each cell meiosis II products So the correct answer is 15 pg Was this answer helpful

Meiosis is called reductional division because number of chromosomes and amount of DNA in daughter cells is reduced to half than that of parent cell In meiosis diploid number of chromosomes is reduced to haploid number Following are the various stages of meiotic prophase I a Leptotene During this stage chromosomes become gradually visible under light microscope The compaction of chromosome continues through this stage The sister chromatids are so tightly bound that one cannot be differentiated from another b Zygotene At this stage chromosomes start forming pairs This
