.5 Monohybrid Ratio
The phenotypic ratio of different types of individuals occurring in the F2 generation of the monohybrid cross is called the monohybrid ratio. In the Mendelian monohybrid experiments, this ratio was always 3:1( i.e., 75% is dominant and 25% is recessive).
For example, for one of his monohybrid crosses, Mendel selected true breeding homozygous parents showing contrasting characters for the height of the plant. He performed the experiment in three stages as described. The result obtained is shown in Figure 7.2 below.
This cross is based on the first law of genetics i.e Law of Segregation. A monohybrid cross is a mating between two organisms with different variations at one genetic chromosome of interest. The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus.
