Chapter 3, Problem 1ER

Summary Introduction

To discuss: The types of cell division.

Introduction:

Cell division:

Cell refers to the basic unit in the body that provides life to all organisms on earth. Cell division refers to the process cellular and nuclear division where the parent cells divides itself into identical daughter cells.

Explanation of Solution

The two types of cell division are as follows:

1. 1. Mitosis: It is a cellular and nuclear division process where the parent cell divides into two identical diploid daughter cells.
2. 2. Meiosis: It is a process where one deoxyribonucleic acid replication and two cellular and nuclear divisions lead to the creation of four haploid gametic cells.

Summary Introduction

To discuss: The influence of each type of cell division on individual genetic variation.

Explanation of Solution

Mitosis helps in the growth and repair of cells. This process produces daughter cells identical to the parent cell. Hence, there is no much influence of mitosis on genetic variation. However, meiosis contributes to genetic variation. During meiosis, homologous chromosomes crossover and lead to deoxyribonucleic acid swap. This results in genetic variation.

Conclusion

Cell division refers to the process cellular and nuclear division where the parent cells divides itself into identical daughter cells. Mitosis and Meiosis are the two types of cell division.
