EXERCISE 5 MENDELIAN TRAITS IN HUMANS 1 While most human traits are polygenic, the traits in the chart below have traditionally been considered Mendelian traits. More recent research has disputed the single-gene nature of some of these traits, but for the purpose of this exercise, assume that the following traits are Mendelian. Work with a partner to help each other determine your own phenotypes and possible genotypes for these traits. Write your answers in the chart. (Note: Refer to the table on p. 62 for information about these traits.) Mendelian Trait Cleft Chin (Dominant) Freckles (Dominant) Attached Earlobes (Recessive) Hitchhiker's Thumb (Recessive) Widow's Peak (Dominant) Your Phenotype Your Possible Genotype(s)

Problem) A university student is studying the inheritance of 2 genes of pea plants. Color of plant:  Blue is dominant (B), and yellow is recessive (b) Spikes or no spikes:  Having spikes is dominant (G), and having no spikes is recessive (g). Which of the following findings would indicate to the student that these two traits are located close together on the same chromosome? a) The traits show independent assortment b) All gametes of a double heterozygous individual (BbGg) are either BG or bg c) A double heterozygous individual has four types of gametes in approximately equal proportions: BG, Bg, bG, and bg d) Student finds that there is frequent crossing over between the 2loci

Thank you.

Practice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.

Thank you.
