What is the key difference between metaphase in Meiosis I versus metaphase in mitosis?
|
|
chromosomes line up single-file in the middle in meiosis I
|
|
|
chromosomes line up double-file in the middle in meiosis I
|
Explanation:
Detailed explanation-1: -In metaphase I, a pair of homologous chromosomes are arranged together while in metaphase of mitosis single chromosomes are arranged in the equator. So in the metaphase plate of metaphase I we can see a line of two chromosomes, while in metaphase of mitosis, a line is consists of single chromosomes.
Detailed explanation-2: -Mitosis: Sister chromatids (duplicated chromosome comprised of two identical chromosomes connected at the centromere region) align at the metaphase plate (a plane that is equally distant from the two cell poles). Meiosis: Tetrads (homologous chromosome pairs) align at the metaphase plate in metaphase I.
