Front

What is another term for the process where part of the genetic information of one chromosome switches places with that of another chromosome?

Back

Genetic recombination

Front

What stage of meiosis is characterized by the formation of two nuclei enclosed by nuclear membranes?

Back

Telophase

Front

What term refers to a cell that has its full or complete number of chromosomes?

Back

Meiosis

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes (2N), while haploid cells have one set (N).

Front

What is the significance of crossing over in meiosis?

Back

Crossing over increases genetic diversity by exchanging genetic material between homologous chromosomes.

Front

What is the result of nondisjunction during meiosis?

Back

Nondisjunction can lead to gametes with an abnormal number of chromosomes, resulting in conditions like Down syndrome.

Front

What is the role of spindle fibers during meiosis?

Back

Spindle fibers help separate chromosomes during cell division.
