Branch of bioiogy that studies heredity (passing of characteristics from parents to offsprings).

Who discovered genetics?

Genetic Terms

Punnett Squares

In the punnett square to the right, P represents the dominant gene of a purple flower and p represents the recessive gene of a white flower. When two heterozygous (Pp) cross the genotypical results of their offsprings are 25% PP, 50% Pp, ad 25% pp. The phenotypical results of their offsprings are 75% purple and 25% white.

Complex Patterns of Inheritance

Sex-Linked Traits

-Characteristics determined by genes on sex chromosomes. -Ex: Red/green colorblindness, hemophilia, male pattern baldness, and placement of sweat glands.
