prophase 1.
breaks off and attach to adjacent chromatids on the homologous chromosome
During the tetrad stage, the metaphase I of meiosis starts to happen. When this occurs, the diploid meiocyte divides twice.
This is the process of crossing over that happens in prophase I.
There are five substages to prophase I. Genetic exchange happens during the fourth stage, Diplonema. This process is also called crossing over.
prophase 1.
prophase I of meiosis I because that is where crossing over occurs
prophase I
breaks off and attach to adjacent chromatids on the homologous chromosome
They do not get multiplied
Crossing over is the process in which babies are made.
Prophase I

Diplotene stage of meiosis I phase
This is the process of crossing over that happens in prophase I.
A sea voyage.
Crossing over isn't neccessarily a named stage but is when alleles "jump" over to other parts of the chromosome resulting in greater genetic variation. That way the population isn't in a word having children with their cousins.
