Punnet Square

Punnet square is used in genetics to predict the outcome of a breeding experiment. It was devised by an English geneticist named Reginald Punnet. The genetic aspect of a living thing is used to determine the probabilities by biologists. Every possible combination of both the genetic parents is analyzed here. These crosses could be monohybrid or dihybrid. Mono hybrid crosses have the dominant and recessive genes of the parents placed separately. For instance B is dominant gene and b is recessive gene. B and b of the mother and that of the father are combined to find the possibilities where BB and bb have 25% chances each while Bb has 50% chances. In case of dihybrids, there are four gene variables instead of two. They are also used in trihybrid cross.

Application of Punnet Square

Punnet squares help one to understand about sex linkage and sex determination. The inheritance capacity of the offspring is determined by these squares. The patterns of family lines are also analyzed here. They help one to understand about inherited diseases and avoid such diseases. A living thing’s best possible genes could be promoted in its off spring through punnet square calculations. Agriculture and Animal breeding could be taken to the next level by the diligent use of Punnet square. Punnet square opens up a lot of possibilities to enhance the future of mankind as well. Punnet square also determines all possible blood types. Human origin is ably traced with the help of these Punnet squares.

Implementing It

Punnet square is also done for diseases like colour blindness and Down’s syndrome. Two or three traits are analysed through these squares. Eye colour is determined by this method. The Punnet square activity games are available for children to work on. Punnet square calculators are available in online sites. Punnet square percentages help the parents to understand probable possibilities of their future generations. The possibility to carry on or cut a particular trait is also possible by Punnet square calculators. Inheritance is a very important aspect of the Living science which could be deftly handled by the decisions made with the help of Punnet square calculations.
