- Subject: Genetic problems 6. how would you recognize a line of garden peas that had become genotypically pure for a given trait? 7. A cross of two pink-flowered plants produces offspring whose flowers are red, pink, or white. Defining your genetic symbols, give all the different kinds of genotypes involved, and the phenotypes they represent. 9. In snapdragons, red flowers (R) are incompletely dominant to white (r), the hybrid being pink; narrow leaves (N) are incompletely dominant to broad leaves (n), the hybrid being intermediate in width ("medium"). show the genotypes and phenotypes for the progeny of a cross between a. red medium and pink medium plant b. a pink medium and white narrow c. two identical dihybrids 12. In guinea pigs, short is dominant to long. A short-haired guinea pig was mated to a long-haired one. What proportions of the offspring (F1) will be expected to be: a. homozygous short-haired b. homozygous long -haired c. heterozygous short-haired d. heterozygous…Sample problems related to non Mendelian inheritanceRead, analyze and answer completely the following problems: 1. Explain why it is possible for the proband in the following pedigree to have children of blood types A, B, and AB. Considering epistatic genes, what are the possible genotypes of II-2? 2. Agouti (A) is wild type and produces alternating bands of pigment on each hair. Black (a) is recessive to agouti. A mutation on gene B (recessive b) can eliminate all color. In a cross between agouti (AABB) and albino (aabb) mice, what genotypes, phenotypes, and proportions are expected in the offspring in F1 and F2 generations?Solve the given Problems: (Put the correct symbolic cross and correct answer to the given questions.) A. The man is heterozygous type B (BO) and the partner is homozygous type A (AA). Do the cross to show how it happens and answer the following: What are the different blood types and the corresponding genotypes of their kids? What is the chance or the probability to have a blood type B child? How about the chance to have a type AB child?

- 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.Problem 1: A pet storeowner mated two guinea pigs with the following results 22 black offspring 5 white offspring He then mated two of the black offspring and got the following results: 16 black offspring 3 white offspring What is the genotype of the parents used in the first cross? What is the genotype of the parents used in the second cross? What is the chance of obtaining a totally homozygous offspring in the second cross? If the white offspring were crossed with the original parents, what would be the probability of obtaining white offspring? What would be the chance of obtaining a homozygous black offspring?Solve the given Problems: A. The man is heterozygous type B (BO) and the partner is homozygous type A (AA). Do the cross to show how it happens and answer the following: What are the different blood types and the corresponding genotypes of their kids?
