Biology Final Review

Which of the following is not part of mitosis?

• cell division

• duplication of chromosomes

• reduction of chromosome number

• production of new cells

What phase is this?

• prophase

• metaphase

• anaphase

• telophase

What is crossing over?

• two homologous chromosomes trade pieces

• genes on chromosomes each shift positions

• a chromosome is removed from a cell's nucleus

• part of a chromosome breaks off

What kind of cells are made at the end of mitosis?

• identical cells

• genetically different cells

• haploid cells

• polyploidy cells

What is a gamete?

• sperm cell

• egg cell

• somatic cell

Why is sexual reproduction advantageous over asexual reproduction?

• Requires less energy

• Higher rate of success producing offspring

• Results in a genetically varied offspring that will have a better chance of survival if the environment changes

• Results in identical offspring
