What is Punnett square?
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.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.learn more about punnett square below,

What are the features of ridges?A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance.
Moreover, four classes of oceanic ridges are considered: spreading-center ridges, fracture-zone ridges, basaltic-volcanic ridges, and island arc ridges.
A ridge is a long and narrow elevation that has steep slopes on either side and stands out from the surrounding lowlands. It also acts as a watershed to rivers that flow down narrow valleys on both of its sides.
