1. What are the major differences between mitosis and meiosis?
Why is it necessary to have a meiotic cell division?
Explain the difference between the C value and the n number.
What phase of the cell cycle does DNA replication occur in?
2. How many chromosomes are found in a normal human cell?
Define the terms "autosome" and "sex chromosome."
Name three ways that one can distinguish one chromosome from another.
3. Explain briefly the stages of the reductional division in meiosis.
Explain the process of crossing over or recombination. Include in your answer chiasma and synatonemal complex.
4. Genes and chromosomes behave in similar ways; explain what this means with regard to Mendel's principle of independent assortment.
5. For each of the following, give a brief description:
Here you go :)
Produces: four haploid daughter cells two diploid daughter cells
Genetically: different identical
Function: Growth, Repair, asexual Reproduction Cellular Reproduction (cell division during which the cell nucleus divides)
Creates: Sex cells only Makes everything other than sex cells (Somatic Cells)
Occurs in: Humans, animals, plants all organisms
Meiosis is a special process in cellular division where cells are created containing gene patterns of different types and combinations with 50% of the number of chromosomes of the original cell. Meiosis is used in sexual reproduction of organisms to combine male and female, through the spermazoa and egg, to create a new, singular biological organism.
C-value refers to haploid amount of DNA
n - number of chromosome sets
The S (Synthesis) period is where DNA ...
