Which of the following best describes meiosis?

• It is carried out in all tissues theat require cell replacement
• It occurs only in cells in the reproductive structures of an organism
• It happens in all of the tissues except the brain and spinal cord
• It is the first stage of mitosis

Which best describes the process shown?

• mutation in which the DNA content of the gene is ltered
• segregation of sister chromatids
• condensation and segregation of the alleles
• crossing-over which alleles are exchanged

Which of the following best explains why the chromosome number is an even number in organisms?

• It is only by coincidence, many organisms have an odd number
• The diploid number is always even so that when mitosis occurs each cell gets the same number of chromosmes
• The diploid chromosome number represents pairs of chromosomes, one from ech parent, so that it is always an even number
• Chromosomes double very time the cell divides, so after the first division, the number is always even
