Punnett square

The key difference between Classical and Modern Genetics is that the classical genetics is the Mendelian genetics or the older concept of genetics, which solely expressed based on the phenotypes resulted from breeding experiments while the modern genetics is the new concept of genetics, which allows the direct.

Changes in the genetic makeup of a population affect the incidence of certain traits and diseases within the population. Beginning with a look at the abnormally high rate of a dangerous health condition in US Amish communities, this module explores forces that affect a population's gene pool. Among them are natural selection, gene flow, and two types of genetic drift: founder effects and bottleneck events. The Harvey-Weinberg Equilibrium equation is presented along with sample problems that…

Punnett's Square Activity - Shows Mendel's Genetics

Punnet Square- is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
