Chapter 6-Diversity and Heredity

Hereditary information is located in 

• chromosomes found on genes
• genes found on chromosomes
• mitochondria
• chloroplasts

In humans mitosis is directly involved in 

• production of egg and sperm
• tissue repair
• sexual reproduction
• meiosis

Asexual reproduction primarily involves the process of 

• ovulation
• fertilization
• meiosis
• mitosis

Compared to the number of chromosomes in a human body cell, the number of chromosomes in a sex cell is 

• the same
• double
• one half
• four times as great

The process of an egg and sperm joining together is 

• mitosis
• meiosis
• cloning
• fertilization

Which type of reproduction involves one parent, no union of gametes, and offspring who are identical to the parent?  

• sexual reproduction
• asexual reproduction

Traits that allow certain organisms to survive in their environment are called

• mutations
• translocations
• translations
• adaptations

Traits that allow certain organisms to survive in their environment are called

• mutations
• translocations
• translations
• adaptations

Mutations are 

• changes in DNA
• traits that are a disadvantage
• traits that are an advantage
• pieces of DNA that can be removed

What can happen to a species if the environment changes and the organisms cannot adapt?

• evolution
• extinction
• reproduction
• succession
