Do somatic cells reproduce asexually? When during meiosis does independent assortment occur? What happens to the gametes if nondisjunction occurs at anaphase 2? What is the parent cell in meiosis? Mitosis produ
How does mitosis make the growth and repair of cells possible in an organism? In the case of multicellular organisms, mitosis helps in growth and repairby producing more number of identical cells. ... The parent cell divides into two daughter cells that are identical to the parent cell during...
Mitosis: Mitosis is the cell division where one diploid cell divides into two diploid cells. All are genetically identical. It is achieved by the parent cell first duplicating its chromosomes and all the cytoplasmic components. Key Terms and Vocabulary ...
In meiosis two, there is no S phase i.e. no duplication of chromosomes. The process is similar to mitosis as the two sister chromatids are separated and the two haploid daughter cells form four haploid (23 chromosomes) cells with single chromatid. This reduction in the number of chromosome ...
2D). After a spontaneous fusion of a micronucleus containing a proto-B chromosome and a standard nucleus, a cell with the haploid number of maternally derived chromosomes and an additional proto-B evolves of mainly paternal origin during early embryogenesis (Fig. 2M). To ensure fertile plants, ...
They are also referred to as sex cells. Female gametes are calledova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis. ...
How many chromosomes are found inside the nucleus of every human cell except egg and sperm cells? In humans, how many chromosomes are in each cell after mitosis? A cell has 16 chromosomes. How many chromosomes would its daughter cells have after meiosis? Which chromosomes in a karyotype are ...
Autosomal Chromosomes: Chromosomes are divided into two types: autosomal and sex chromosomes. Sex chromosomes are those that determine whether the human is male or female. If the person receives two X chromosomes, it will be female, and if it gets one X and one Y it will be male. ...

Explain why mitosis can occur in a haploid cell, but meiosis can't. What is the difference between mitosis and meiosis in relation to cell division? Why is cell division important? What are the basic details of cell division? Does mitosis create a cell that is different or the identical...
