Can u plzzz briefly explain punnett's square theory...... Cannot understand anything..plzzzzz
Answers
A Punnett square is a graphical representation of the possible genotypes of an offspring arising from a particular cross or breeding event. Creating a Punnett square requires knowledge of the genetic composition of the parents. The various possible combinations of their gametes are encapsulated in a tabular format. Therefore, each box in the table represents one fertilization event.
The inherent assumption is that each trait is determined by a single gene locus and that various traits assort independently from one another. Though this is true for many useful traits, especially when choosing characters for plant or animal breeding, there are many exceptions.
This tool was created in the twentieth century, much after Mendel’s seminal experiments on genetics. However, they are now commonly used to explain the results that Mendel obtained, especially when combined with our current knowledge of DNA, genes and chromosomes.
