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

Based on the data shown in Table 5, is it possible to determine the genotypes of all flies showing the dominant trait? Why or why not? 2.

8.Using Punnett squares, phenotypes, and genotypes, show me the difference between incomplete dominance and codominance. 10. From your textbook, you learned about sex-linked traits using Drosophilia eye color. For this question, we are going to look into sex-linked traits in humans. Color blindness is more often seen in males than in females. Using a Punnett square, demonstrate how this observation is supported using the concepts we’ve been practicing in this assignment.
Explain the possible reasons for the observed differences in the sample means. Account for the differences in the sample means of P1 and P2. Similarly, account for the differences in the sample means of the F1 and F2. Compare the difference in the parental generations with that in the filial generations.
The next two questions go together. Suppose the tail length of two populations of lizards is controlled by one gene. To determine the mode of inheritance, a true-breeding short-tailed female is crossed with a true-breeding long-tailed male. Then, siblings from the F1 are crossed and the number of short- and long-tailed animals are counted to determine the phenotype ratio. 1. What phenotypic ratio do you expect in the F2 generation if tail length is controlled by an autosomal gene, and long tails are dominant to short tails? 1 long: 1 short males 1 long: 1 short, females all short O 3 long: 1 short O 1 long: 3 short

13. In another species of berry, Rass berrylis, the allele for yellow fruit (F) is dominant to the allele for red fruit (f), and the allele for thorny stems (T) is dominant to the allele for thornless stems (t). The gene for fruit colour is 17.4 map units from the stem thorniness. gene for a. Draw a Punnett square to illustrate the cross between a Rass b. with red berries and thornless stems and a plant that was heterozygous for both characteristics. (The parents of the heterozygous plant were yellow-fruiting and thorny, and red- fruiting and thornless, and were homozygous for both traits.)
If we neglect any possible environmental effects, dominance, linkage, or epistasis, and assume that each effective allele makes the same additive contribution, how many pairs of polygenes are involved?
