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. Consider the beetle species in Model 1.a.How many phenotypes for exoskeleton color are exhibited in the population?b.How many genotypes for exoskeleton color are exhibited in the population?2. According to Model 1, which allele, B or b, is the dominant exoskeleton color allele? Justify youranswer with specific evidence from Model 1.Basonly1isneededwhitewhiteonYshowsupwith2b'sBBBbBbbb23I

The Punnett squares in Model 1 show the possible outcomes for an offspring resulting from themating of two beetles.a.Which Punnett square shows a cross between two homozygous beetles?b.Which Punnett square shows a cross between a heterozygous beetle and a homozygous reces-sive beetle?
