Meiosis

one of different forms of a gene

• allele

• gene

• crossing over

• meiosis

Errors that lead to an incorrect number of chromosomes usually occurs and which stage(s) in meiosis?

• Prophase I only

• Metaphase I / Metaphase II

• Anaphase I / Anaphase II

• Telophase II only

process in which homologous chromosomes exchange portions of their chromatids during meiosis

• mitosis

• gene splicing
• crossing over

• meiosis

True or False: Crossing-over occurs after anaphase of mitosis while crossing-over occurs before anaphase I of meiosis.

• True

• False

specific characteristic of an individual

• synapsis

• tetrad

• allele

• trait

structure containing four chromatids that form during meiosis

• synapsis

• tetrad

• diploid

• haploid

True or False: In anaphase of mitosis, sister chromatids separate. In anaphase I of meiosis, homologous chromosomes separate.

• True

• False

Which three processes occur during meiosis?

• Production of diploid cells

• Asexual Reproduction

• Independent Assortment

• Crossing Over

• Formation of Gametes

True or False: Meiotic cell division results in gametes that produce sperm and egg cells by increasing the daughter chromosome number by 50%

• True

• False

the fusion of homologous chromosomes

• cytokinesis

• gene

• tetrad

• synapsis
