A turkey farmer is worried about a new disease that is found in his birds. If affects females more than males. Which of the following is(are) reason(s) that explain this finding? The disease is sex linked b The disease is autosomal recessive  c The disease is located on the Z chromosome d A and C e B and C

2. For each genotype, identify whether it is haploid or diploid. Haploid or diploid? Ss Haploid or diploid? WW Ww rr Ww Tt W Ts wH 3. For each genotype, identify whether it is homozygous dominant (HD), heterozygous (Ht) or homozygous recessive (Hr). HD, Ht or Hr? HD, Ht or Hr? Ss WW GG Pp XHXh rr X:X: LL

Smaug (The Chiefest and Greatest of Calamities, The Unassessably Wealthy, The Stupendous, etc.), is the dragon who lords over the Lonely Mountain in J.R.R. Tolkien's The Hobbit. He is described with the following phenotypes: Reddish-golden scales Batlike wings Fire breathing Let's assume the following inheritance models are true for the dragon phenotypes observed: Phenotype Scale Color Wing Shape Fire Breathing Alleles R¹ (Red scales), R² (Gold scales) X¹ (Bat-like, Dominant), Xi (Insect-like, Recessive) F (Fire breathing), f (unable to create fire) Inheritance Model Incomplete dominance X-linked allele Mendelian

5. In German cockroaches, bulging eyes (bu) are recessive to normal eyes (bu*), and curved wings (cv) are recessive to straight wings (cv*). These two traits are encoded by autosomal genes that are linked. A cockroach has genotype butbu cv*cv, and the genes are in repulsion. Which of the following sets of genes will be found in the most common gametes produced by this cockroach? a. buʻcy+ b. bu cv с. butbu d. cv*cv е. bu cvt

6. There are two enzymes LDH1 and LDH2. The gene that encodes this enzyme is X-linked. You extract the enzyme from different cells in several people and carry out electrophoresis. Give the genotypes for each person Draw the banding pattern that you would expect in the gel. Male with Male with Female Female Heterozygous LDH1 gene homozygous female LDH2 homozygous for LDH2 for LDH1

2. An organism is 2n=4 with genotype AaBbEe. Genes A and B are close together on the larger chromosome, and gene E is on the smaller chromosome. a. Using a vertical metaphase plate, draw the two independent orientations of this AaBbEe cell in Metaphase I of Meiosis. b. Label alleles on all chromatids. c. Write the alleles in each possible gamete on the lines below each orientation. OR O'Q ( Gametes:
