Learning about Heredity

This topic is about how can we predict traits. Something that we need is the probability. Probability is something that will happen or also called chance.How do we predict inherited traits? We can predict inherited traits by a table called Punnett square. In the Punnett square we used two letters: capital letter and lowercase letter. The capital letter means dominant trait and the lowercase letter means recessive trait. What is a pedigree?  A pedigree is a chart of the trace of a family history. For the chart we used: circles, squares, vertical lines, and horizontal lines. The circles mean the mother, the squares mean the father, the vertical lines marrige, and the horizontal lines their children. Inside the pedigree some individual are called carriers. And for last is the incomplete dominance. The incomplete dominance results when no one of the traits complete the other.
