  2. When we say that “Tt” causes tall plants, “Tt” represents a: • Phenotype b) genotype c) karyotype d) pedigree 2. One of 2 alternate forms of a single gene is called a(n) _______________? 3. Using the allele key “B= large beak, b=smaller beak” describe the following: • A homozygous dominant genotype • A purebred recessive genotype • Give the phenotype of a hybrid

  3. 4. The genotype Aa can be described as _______? 5. A _____ allele is one whose trait always shows up in the organism when the allele is present. 6. The genotype PpLLAaNnTT: • Has how many genes in it____? • Is diploid or haploid?

  4. 7. Write the 4 steps to completing Punnett Squares. 8. In Newts Rough skin (R) is dominant to smooth skin (r). If Tyrone the smooth skinned newts has offspring with Nanda, a newt who carries the recessive allele but is rough-skinned. What are the chances of homozygous offspring? (Show all work) 9. EC: What 2 processes of sexual reproduction are demonstrated inside and outside punnett squares? 10. EC: For the wildflower genotype PpLLAAnnTT, find the possible gametes.

  5. Key • A 2) allele 3A) BB 3B)bb 3C) Large 4. Hybrid or heterozygous 5. Dominant 6A. 5 genes 6B. Diploid 7. Create allele key, find parent genotypes, meiosis, fertilization 8. 50% chance 9. Meiosis and Fertilization 10. PLAnT, or pLAnT
