Summary Introduction
To explain:
The relation between the results of a dihybrid cross and meiosis events.
Introduction:
Meiosis:
In this type of cell division, there occurs production of four daughter cells. These daughter cells contain half the number of chromosomes than the parent cell. It occurs in the gametes and plant spores production.
