genetic variations in What you will do Activity 2.1 Can you do this? Write the correct answers under each column. If you find difficulty, review the lesson on mitosis and meiosis. Mitosis Meiosis Basis of Comparison 1. Type of cell where the process occurs 2. Number of cell division 3. Number of chromosomes (2 sets/1 set) 4. Number of daughter cells produced per parent cell To further familiarize you with the process of cell division, here's another activity.

Answer:
1. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. ... A large structure called the mitotic spindle also forms from long proteins called microtubules on each side, or pole, of the cell.
During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
2. two
Mitosis produces two daughter cells that are genetically identical to each other, and to the parental cell. four
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
3. 46 chromosomes
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes. 23 chromosomes
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.
4. Two daughter cell's in mitosis and four daughter cell's
