Calculate Mendelian Ratio







Formula

The formula to calculate the Mendelian Ratio (MR) is:

\[ \text{MR} = \left(\frac{A}{T}\right) : \left(\frac{B}{T}\right) : \left(\frac{C}{T}\right) : \left(\frac{D}{T}\right) \]

Mendelian Ratio Definition

A Mendelian ratio refers to the predictable patterns of inheritance observed by Gregor Mendel in his genetic experiments with pea plants in the 19th century. These ratios, such as the 3:1 ratio seen in monohybrid crosses or the 9:3:3:1 ratio seen in dihybrid crosses, represent the statistical probability of offspring inheriting a particular combination of traits from their parents. These ratios are foundational principles in the field of genetics.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{MR} = \left(\frac{90}{160}\right) : \left(\frac{30}{160}\right) : \left(\frac{30}{160}\right) : \left(\frac{10}{160}\right) = 0.56 : 0.19 : 0.19 : 0.06 \]

The Mendelian Ratio (MR) is 0.56 : 0.19 : 0.19 : 0.06.
