Question

How are the pairs oriented in respect to the poles of the cells?

a) Parallel to the poles
b) Perpendicular to the poles
c) Diagonal to the poles
d) Randomly oriented

Answer 1

During metaphase I of meiosis, the orientation of homologous chromosome pairs is random with respect to the cell's poles, contributing to genetic diversity through Mendel's law of independent assortment.

Step-by-step explanation:

The question pertains to the orientation of chromosome pairs during metaphase I of meiosis. This is a key process in cell division that ensures genetic diversity through independent assortment. During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The orientation of each pair of homologous chromosomes at the center of the cell is random in relation to the poles, which underlies Mendel's law of independent assortment.
