Meiosis and Genetics

CROSSING OVER INCREASES

• LIFE SPAN

• GENETIC VARIATION

• THE NUMBER OF OFF-SPRING

• ALL ARE TRUE

WHAT TYPE OF CELLS STORE THE GENETIC INFORMATION THAT IS PASSED TO OFF-SPRING

• BODY CELLS

• MITOSIS

• EGG

• SPERM

• EGG AND SPERM

What causes genetic variation in meiosis?

• chromosomes lining up
• crossing over of chromosomes
• separation of chromosomes
• chromosomes pulling apart

Chromosomes exchange genetic material during 

• crossing over
• replication
• synthesis
• translation

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

The result of meiosis is:

• two diploid cells
• two haploid cells
• four diploid cells
• four haploid cells

The cells produced via meiosis are called:

• gametes
• somatic cells
• body cells
• skin cells

Which process and type of resulting cells are represented?

• mitosis, gametes
• mitosis, body cells
• meiosis, gametes
• meiosis, body cells

What causes genetic variation in meiosis?

• chromosomes lining up
• crossing over of chromosomes
• separation of chromosomes
• chromosomes pulling apart

Crossing over helps promote 

• male genotype
• genetic variation
• DNA replication
• mitosis
