AP Biology 5.1 Meiosis and Chromosome Transmission

Practise AP Biology 5.1 questions by tracing meiotic divisions, chromosome separation and the distinct haploid outcomes of meiosis and mitosis.

Exam points

calculate chromosome-number changes through DNA replication, meiosis and fertilization
explain how homologous-chromosome pairing and ploidy affect successful gamete production
compare spindle attachment, chromosome alignment and separation in mitosis and meiosis

Covered syllabus points

5.1.A—Explain how meiosis results in the transmission of chromosomes from one generation to the next 5.1.B—Describe similarities and differences between the phases and outcomes of mitosis and meiosis

Which of the following best explains why triploid bananas do not produce seeds?

The cells of the banana plant are unable to replicate DNA, thus preventing cell division and limiting growth.

The banana plants lack enough genetic diversity to properly hybridize.

The production of gametes is disrupted because of unequal pairing of homologous chromosomes during meiosis.

The production of seeds is not required because triploid plants produce gametes without fertilization.

[Maximum number: 2]

Both mitosis and meiosis are forms of cell division that produce daughter cells containing genetic information from the parent cell.

Describe TWO events that are common to both mitosis and meiosis that ensure the resulting daughter cells inherit the appropriate number of chromosomes.
