Somatic cells, such as blood cells and skin cells, are and are produced by . A different process called is required to create such as sperm and egg, because these cells are
This Venn diagram could be used to visually compare mitosis and meiosis. The area in the middle, where the two circles overlap, represents facts that are true of both processes. Which of the following statements should be written in the middle area?
A genetics student extracted the chromosomes from a somatic cell of an organism for analysis. She discovered that two of the chromosomes were the same size, contained the same amount of DNA, and contained the same genes located in the same positions on both chromosomes. Which of the following terms should she use to describe these chromosomes?
Why is a zygote (the results of egg + sperm combining) diploid?
What process is being shown?

The following abnormality occurs 1:1000 live births - healthy and fertile - and usually cannot be distinguished from a normal person except by karyotype. Individuals with this chromosomal condition don't experience symptoms or have only mild symptoms. In others, symptoms may be more apparent — possibly including developmental delays and learning disabilities.
What is the gender of this person?
How many total chromosomes are present?
When does this process occur?
What is the importance of this process?
Is this karyotype from a male or a female?
Are there any chromosomal abnormalities visible?
