What type of cells does mitosis produce? In which stage of mitosis does the exchange of genetic material between chromosomes (crossing over) occur? A. prophase I B. prophase II C. anaphase I D. none of the above During meiosis, when do homologous chromosomes separate from one anot...
What process in meiosis can change the combination of alleles among linked genes? What is fertilization? Where does it take place? Do all plants fertilize? Which of the following are produced by meiosis? a. haploid cells b. eggs c. sperm d. plant spores e. all of these ...
To answer the question regarding the type of cell division that occurs in the cells of the upper layer of the epidermis, cells of the lining of the gut, and blood cells, we can follow these steps:1. Identify the Types of Cells:
The G1, S and G2phases are collectively termed interphase. The rest of the cell cycle is concerned with cell division – mitosis in somatic cells, meiosis in the specialized cells of gonads. The stages of mitosis and meiosis are collectively called the M phase, potentially introducing confusion...
Meiosis begins with aparent cellthat is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. What cells in the human body are multinucleated?
1. All living things are made up of cells. 2. Cells are the basic building blocks of life. 3. All cells come from preexisting cells created through the process of cell division. As science evolved, three more components were added to the theory.Some biology classes don’t require you to...
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have onlyone set of chromosomes: they are haploid. They have undergone a process of cell division calledmeiosis. During meiosis, crossing over occurs. This make...

Mitosis involves a single cell division that results in two identical daughter cells, while meiosis consists of two successive divisions, producing four genetically distinct gametes.
