summary #6: predicting traits

What probability have a person that his son be like him? The only way we can predict that is with a Punnett square. A punnett square is a table usad to prdict the outcome of crossing differents forms of a trait.In a Punnett square, we use capital letters for dominant traits, and a lowercase letter is a recessive trait. To create a Punnett square the only thing we have to do is to draw a large square and divide it into four. Write the parent's factor for the trait outside the square, that will predict if the kid will be like his mother or his father.

The pedigree is a chart used to trace the history of traits in a family. For example, my family have pedigree for brown eyes, noy I am carrier of that pedigree, but if my son will have green eyes, but if my wife don´t have green eyes, there is incomplete dominance. Incomplete dominance is a genetic pattern which neither of the two forms of a trait completely mask the other.
