How does cell division produce identical cells? Why is cytokinesis a necessary part of cell division? When, where, and why does mitosis occur in multicellular organisms? What are the different steps that are involved in mitosis? Explain both meiosis and mitosis. How is the chromosome number...
The life cycle starts when diploid sporophytes divide by meiosis giving rise to haploid spores with half the number of chromosomes. Through mitosis, spores develop into multicellular gametophytes, which then produce haploid gametes. Fertilization happens when two haploid gametes come together forming dip...
How does sexual reproduction and meiosis leads to genetic recombination? Explain. How does meiosis contribute to genetic diversity? How does the process of meiosis contribute to the genetic variation of Sordaria? Explain why meiosis leads to significant genetic variation while mitosis does not. Explain...
During meiosis I, the chromosome number is halved, resulting in haploid cells. Therefore, the secondary spermatocyte will have 15 chromosomes (n). - Each secondary spermatocyte then undergoes meiosis II to produce spermatids. Since meiosis II does not change the chromosome number, the spermatids...
In other Web pages, you have learned how to make male sperm, fix male sperm, and enhance male sperm, focusing on pre-sperm male germ cells. How does that help us make female sperm? We once again turn to the work of Professors Ralph Brinster and James Zimmermann at the University of ...
(In the unisexual vertebrates, for example, it has been argued that the hybridizing species need to be genetically close enough to produce a viable hybrid but far enough to disrupt meiosis [43, 75] and/or satisfy more specific restrictions [76].) To be sure, other explanations have been ...

How many haploid cells are produced during meiosis I? a) 1 b) 2 c) 3 d) 4 How many chromosomes does each daughter cell contain? Somatic cells of the fruit fly have 8 chromosomes. How many sex chromosomes are in a somatic cell?
If a cell has 30 chromosomes before mitosis, how many does each daughter cell have afterward? How many chromosomes do primates have? How many chromosomes are in a cell at the beginning of meiosis? A horse has 32 chromosomes in all of its body cells. How many...
If a cell has 30 chromosomes before mitosis, how many does each daughter cell have afterward? How many copies of a gene do somatic cells have? Three cells undergo meiosis. How many haploid cells are produced? How many chromosomes will be found in each cell after telophase/cytokinesis is comp...
