What is random assortment?

• The destruction of genetic material

• The creation of identical daughter cells

• The exchange of DNA sections between chromosomes

• The process where chromosomes line up randomly during cell division

How does random assortment contribute to genetic variation?

• By ensuring all daughter cells are identical

• By randomly lining up chromosomes during cell division

• By creating new proteins

• By destroying unnecessary DNA

What is an example of a trait that can vary due to random assortment?

• Type of cell membrane

• Amount of cytoplasm

• Shape of eyes

• Number of chromosomes

What is crossing over?

• The process where chromosomes exchange sections of DNA during cell division

• The destruction of genetic material

• The creation of identical daughter cells

• The random lining up of chromosomes

How does crossing over contribute to genetic variation?

• By creating new proteins

• By ensuring all daughter cells are identical

• By mixing up genetic information between chromosomes

• By destroying unnecessary DNA

What happens to chromosomes during crossing over?

• They create new proteins

• They line up randomly

• They exchange genetic information

• They are destroyed

Which two processes contribute to genetic variation?

• Mitosis and Meiosis

• DNA replication and Protein synthesis

• Cell growth and Cell death

• Random assortment and Crossing over
