6.1 Meiosis Questions:

1. What is the purpose of Meiosis?
Answer: The purpose of Meiosis is to create new cells with half the amount of chromosomes. Without meiosis the sperm cell and the egg cells joining during fertilization it would produce to time the amount of chromosomes instead of one half of the original number of chromosomes.

2. How do cells at the end of Meiosis differ from the cells at the end of Mitosis?
Answer: In Meiosis after the DNA replicates it goes into to daughter cells. After that those two daughter cells split into two groups of two daughter cells, meaning there is now four daughter cells. At the end of
Mitosis it is different than Meiosis. At the end of Mitosis, there are two daughter cells unlike Meiosis.       









3. What is a Gamete?
Answer: A gamete is what carries haploid chromosomes. These gametes are specialized for reproduction. In animals gametes in males are called sperm cells. In females the gamete cells are called egg cells. The gametes are necessary for reproduction.

4. How are diploid cells and haploid cells different? What human cells are examples of each?
Answer: Diploid cells are different from haploid cells. Diploid is having two sets of homologous chromosomes. Haploid is having one set of daughter cells. (4 daughter cells). A human example of Haploid cell is the sprem and egg cells. A human diploid cell carries two sets of chromosomes.

5. How many phases are there in Meiosis? Why is each phase important?
Answer: There are 5 phases in Meiosis. These phases are, Prophase, Metaphase, Anaphase, Telophase and Cytokenisis. Each phase is important as if one stage was missing cells would not be able to reproduce which means no new cells would be made. Each phase changes a part of the cell. Say if there was no Cytokenisis the cells would not be able to separate into more daughter cells.

6. Why do two brother look different from each other if they came from the same parents?
Answer: A person has a set of chromosomes. One from their mum and one from their dad that join together to make that child. The two halves are joined together and the middle of each chromosome has genes and every DNA has two copies of each gene one of those genes is more dominant that the other. The dominant gene is what makes everyone different. The gender of the child is random. You could say nature chooses one half and that is the gender. of traits are taken from the mother and father. Also  This means that every sperm cell contains a random mix of the father's parents' genes. The same thing happens when forming eggs. Therefore, each child that a couple produces is a random mix of the four grandparents' genes.
