As a result of meiotic division, the chromosome number is

halved

Reduction division occurs during

Meiosis

Meisis results in a change in chromosomal number as shown by

2n to n

Meiosis differs from mitosis in that

it occurs in the formation of gametes

True or False Meiosis-daughter cells with twice the chromosome number as the mother cell

False

Crossing-over

Is a way to recombine the genetic material during meiosis

During cross-over

recombination occurs between the genes on the sister chromatids of homologous pairs.

One duplication of chromosomes followed by two subsequent reduction divisions occurs

only in meiosis

Tetrads are seen

during meiosis I

During meiosis II

chromatids separate

Why do homologous chromosomes pairs in prophase I and not in prophase II

The cells are haploid during prophase II and therefore can't pair.

An error in meiosis that results in an abnormal number of chromosomes in the final haploid cell

~can result from the failure of chromosomes to move to opposite poles during meiosos I and II
~is a condition called aneuploidy
~can result form nondisjunction

In plants, the direct result of meiosis is the porduction of gametes. True or False

False

During which phase of meiosis does crossing over occur?

Prophase I

True or False: Meiosis involves two nuclear divisions without having DNA replication occurring between meiosis I and II

True

A single diploid cell is divided into two haploid cells during

crossing over

Daughter nuclei form from each parent cell during

telophase I and telophase II

Tetrads form during

Prophase I

In which stage are duplicated chromosomes singly lined up during meiosis

only metaphase I
