Final answer:
Human traits that follow simple Mendelian patterns are usually studied using pedigree analysis, Punnett squares, and test crosses.
Step-by-step explanation:
Human traits that follow simple Mendelian patterns are usually studied using pedigree analysis, Punnett squares, and test crosses. Pedigree analysis involves studying the inheritances of traits through generations of a family. Punnett squares are used to predict the possible outcomes of genetic crosses based on the rules of probability and meiosis. Test crosses help determine whether an individual is homozygous or heterozygous by crossing it with a homozygous recessive individual.
