1. Describe scaling relationships. What is isometry, hypoallometry, hyperallometry?

5. solve and discuss genetics problems illustrating the different types of gene interactions, interpret results and infer relationships related to dominance, sex linkage, recombination etc

1. In a wild strain of tomato plants, the phenotypic variance for tomato weight is 3.2g². In another strain of highly inbred tomatoes raised under same environmental conditions, the phenotypic variance is 2.2 g². With regard to wild strain a. What is VG b. What is h₂² C. Assuming that all of the genetic variance is additive what is h²

Answer is: incomplete dominance, variable expressivity because in incomplete dominance, heterozygotes have a phenotype in between the homozygous dominant and recessive (described here as "less hair"). In variable expressivity, individuals with the same genotype have variations in severity of the same phenotype. Both of these characteristics are displayed in this example.

How are these examples of phenotypic plasticity? 1. Haman weight 2. UV exposure 3. Flower color/pH

Use the data to answer the 4 questions in the photo. Answer them correctly and completely.

1. In our classroom for most traits, were there more students with dominant or recessive phenotype? 2. Was there an instance where there were more students with dominant phenotype but more recessive alleles? (q larger than p?) 3. How is this possible?

22.

How can you recognize codominance?   Group of answer choices 1. The heterozygote expresses the phenotypes coded for by both alleles 2. The phenotype of the heterozygote is intermediate between the 3. phenotypes of the homozygotes. 4. The alleles affect more than one trait. 5. The trait exhibits continuous variation

Hello Heliodors! (cont.) Trait A For Heliodors, having four arm-like extensions is dominant over having two. In a family of Heliodors, Hayden has four arm-like extensions like his mother Helen. His father, Harry, and sister, Holly both have two. What are the genotypes of everyone in this family of Heliodors? What is Hayden's genotype? O Not enough information to determine. AA (homozygous dominant) Aa (heterozygous) aa (homozygous recessive)
