The Statistics of Inheritance1The Statistics of InheritanceHow can statistics help predict the traits of offspring?Why?The randomization of alleles from the parents’ genetic material is essential to the survival and evolution ofa species. If the combinations of alleles that make up the genetic material in a zygote are truly random, thelaws of statistics can be used to predict what traits the offspring will have. This activity starts with a reviewof Punnett squares, which is one way to make predictions about simple allele combinations. Statistics willthen be used to make mathematical predictions about the genotypes of offspring.Model 1 – Punnett SquaresBBBbbbBBBBBBBBBBBBBBBbBBBbBbBBBbBbPhenotype GenotypeCross ACross DCross BbbBbBbBbbbbbCross CMaleFemale1.
