Mitosis Meiosis Number of cell divisions Number of daughter cells Ploidy of daughter cells Meiosis.l Type of Chromosomes Alignment at metaphase plate: Meiosis II Exchange of genetic material between chromosomes? When? Meiosis.I Do sister chromatids or homol chrom. separate during division? Meiosis II How do daughter cells compare genetically?

Explanation / Answer

Ans.28

Type of chromosome alignment at

metaphase plate

Individual chromosomes with there sister chromatids attached to a single centromere align. no pairing of chromosomes

Meiosis I - homologous chromosomes pair and then segregate from each other i.e., homologous centromeres align when chromosomes are paired.

Meiosis II - Individual chromosomes with there sister chromatids attached to a single centromere align. no pairing of chromosomes

Do sister chromatids or homologous chromosomes separate during

division?

Meiosis I - homologous chromosomes separate

Meiosis II - sister chromatids separate

How do daughter cells compare genetically

Mitosis Meiosis Number of cell divisions one two Number of daughter cells two four Ploidy of daughter cells diploid haploid

Type of chromosome alignment at

metaphase plate

Individual chromosomes with there sister chromatids attached to a single centromere align. no pairing of chromosomes

Meiosis I - homologous chromosomes pair and then segregate from each other i.e., homologous centromeres align when chromosomes are paired.

Meiosis II - Individual chromosomes with there sister chromatids attached to a single centromere align. no pairing of chromosomes

Exchange of chromosome materials between chromosomes? when? No exchange exchange during pachytene stage of prophase I of meiosis I

Do sister chromatids or homologous chromosomes separate during

division?

Sister chromatids separate

Meiosis I - homologous chromosomes separate

Meiosis II - sister chromatids separate

How do daughter cells compare genetically

daughter cells are Genetically identical daughter cell are not genetically identical due to the cross-over event during meiosis I
