Question

Rachael is observing a few slides taken from a female orangutan. She observes an ovarian slide where all the cells show chromosome tetrads in synapses. Which stage of meiosis has Rachael observed?

Answer 1

Rachael observed the stage of Prophase 1.

Answer 2

The correct answer is:

Meiotic prophase I

Explanation:

The cause that it is Prophase 1 is that the stage shows the chromosomes spanning close to cross over genetic information before they are solidified into the center of the cell to split, which is the stage of Metaphase 1.Synapses just shows that homologous pairs connecting with each other. This could only suggest that they are crossing over which issues in Prophase 1. Also, in Prophase II when the cell has beforehand divided it would no longer be in tetrad form. Metaphase is when the homologous pairs get pulled aside.
