Mitosis and Meiosis Review

Dante wants to match the types of cells with how they are produced. Which choice correctly pairs a type of cell with how it is produced?

• egg cell—meiosis in males
• sperm cell—mitosis in males
• body cell—mitosis in females
• body cell—meiosis in females

If a sexually reproducing organism has 28 chromosomes in its body cells, how many chromosomes did it inherit from each parent? 

• 7
• 14
• 16
• 28

DNA contains genes that provide instructions for inherited traits. What is the relationship between the genes and chromosomes?

• Genes are segments of DNA that are located on the chromosomes of each cell.
• Genes are made up of thousands of chromosomes.
• Genes correspond to the phenotype, while chromosomes correspond to the genotype.
• Chromosomes correspond to the phenotype, while genes correspond to the genotype.

This image shows the chromosomes in a human cell. Which pair of chromosomes controls the development of sex characteristics?

• 1
• 9
• 20
• X/Y

Ryan notices that all of his friend’s brothers and sisters are tall. What is the most likely explanation for this characteristic?

• They have tall parents.
• They have identical genes.
• They eat only healthy foods.
• They live in the same environment.

Which statement correctly describes a type of cell division?

• Mitosis involves one cell division that produces four cells.
• Meiosis involves one cell division that produces two cells.
• Mitosis involves two cell divisions that produce two cells.
• Meiosis involves two cell divisions that produce four.

Which of these choices describes a segment of DNA that determines a specific trait in a person, such as attached earlobes?

• a gene
• a phenotype
• a chromosome
• a characteristic

Which of these statements correctly describes a difference between asexual and sexual reproduction?

• Asexual reproduction increases genetic diversity, but sexual reproduction does not. 
• Asexual reproduction involves one parent, and sexual reproduction involves two parents. 
• Asexual reproduction increases a species’ chances of surviving unfavorable conditions, but sexual reproduction does not. 
• The offspring produced by asexual reproduction are not identical to each other, but those of sexual reproduction are identical to each other. 

Noriko discovers a new plant in a forest. She observes it for some time, and when it reproduces, she tests the offspring and finds that they are genetically identical to the parent. Which of these statements is true about Noriko’s find?

• The plant reproduces sexually, and two parents are required. 
• The plant reproduces asexually, and two parents are required. 
• he plant reproduces sexually, and only one parent is required. 
• The plant reproduces asexually, and only one parent is required.
