Law of Segregation

Definition

noun

Gregor Mendel's law stating that paired alleles separate during gamete formation. Consequently, each gamete would contain only one copy of every paired unit factors.


Supplement

This theory was found true when meiosis was extensively delineated in the following years. During anaphase II of meiosis, the genes on the homologous chromosomes separate as the homologous chromosomes move apart from each other toward the opposite sides of the dividing cell.

The Law of Segregation holds that the zygote formed from the union of gametes from its parents during fertilization contain unit factors (now called genes) are pure or remained uncontaminated from the time that the zygote is formed through the time that it grows and develops toward maturity. At the time that the offspring produces its own gametes, members of these paired unit factors segregate from one another and enter independently into the newly formed gametes.

Re:

... of crossing over occuring in meiosis I in each of the cells and the fact that each of the cells is already different because of the independent segregation in anaphase I. If crossing over was exactly the same in every cell in meiosis I and there was no independent segregation, then we could ...
