The Statistics of Inheritance How can statistics help predict the traits of offspring? Why? The randomization of alleles from the parents’ genetic material is essential to the survival and evolut... ion of a species. If the combinations of alleles that make up the genetic material in a zygote are truly random, the laws of statistics can be used to predict what traits the offspring will have. This activity starts with a review of Punnett squares, which is one way to make predictions about simple allele combinations. Statistics will then be used to make mathematical predictions about the genotypes of offspring.

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 your answer with specific evidence from Model 1. https://www.coursehero.com/file/43088308/19-The-Statistics-of-Inheritance-Spdf/ This study resource was shared via CourseHero.com2 POGIL™ Activities for AP* Biology 3. The Punnett squares in Model 1 show the possible outcomes for an offspring resulting from the mating 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 recessive beetle? 4. Briefly describe how the genotypes inside of the Punnett squares representing the possible outcomes for an offspring are determined. 5. Complete the Punnett square for cross D in Model 1. Include drawings to show the phenotypes possible for the offspring that would result. 6. Refer to Model 1. a. In which of the crosses is there a 100% chance that the [Show More]
