  1. How do we find the probability of traits in our offspring? Sit in your correct seat. Do your DSR question.

  2. Agenda • Today we will practice more punnett squares. • 8.3.7 Recognize and explain that small genetic differences between parents and offspring can accumulate in successive generations so that descendants may be different from their ancestors. • DSR • Review Vocab • Wuggygumples Modeling • Wuggygumples Punnett Practice

  3. Homozygous vs. Heterozygous Show me the genotype for homozygous wings. Show me the genotype for no wings. Show me the genotype for heterozygous wings. Show me the genotype for wings. Show me this wugglegumple’s genotype for polka dots. Show me this wugglegumple’s genotype for skin color. Show me this wugglegumple’s genotype for stars on belly. recessive DOMINANT

  4. Wuggygumples Modeling: What is the probability that two purebred wuggygumples will have babies with no horns? h h h h h h H H H H H H

  5. Steps to solve a Punnett Square • 1.Read the problem • 2. Find the genotypes of the parent • 3. Write down your "cross" (mating)4. Draw a Punnett Square5. "Split" the letters of the genotype for each parent & put them "outside" the Punnett Square6. Slide & Drop fill the Punnett Square7. Analyze the Punnett Square (What are the predicted genotypes & phenotypes of offspring?)

  6. Practice Modeling If a heterozygous polka dotted wuggygumpleand a wuggygumple with no polka dots mate, predict the polka dots of their offspring. Your TURN!! Do the Wuggygumples page.
