Question
Chapter 10.5, Problem 2C
Summary Introduction
To determine: The way by which meiosis and fertilization maintain the normal chromosome number when a sexually reproducing organism like protists is haploid throughout most of its life cycle.
Introduction: In the process of cell division, the chromatin present in the nucleus shrinks and forms a thread like structure called the chromosomes. Cells divide either by mitosis or meiosis processes. A protist is a eukaryotic organism that is distinct from animal, plant or
