Two recessive traits in mice are droopy ears and flaky tails. A true-breeding mouse with norma ears (De) and a flakey tail (ft) was crossed to a true-breeding mouse with droopy ears (de) and normal tail (Ft). The F1 offspring were then crossed to mice with droopy ears and flaky tails. This cross produced the following 100 offspring... 4 droopy ears, flaky tail 2 normal ears, normal tail 46 normal ears, flaky tail 48 droopy ears, normal tail 1) Looking at the offspring, do you believe the genes are linked or unlinked? Support your answer. 2) What is the genotype of the P1 generation organisms? 3) What is the genotype of the F1 generation?

In guinea pigs, rough coat (R) is dominant to smooth coat (r). If a homozygous rough-coated animal is crossed with a smooth-coated one: What will be the phenotype(s) of the F1 generation? What will be the phenotype(s) of the F2 generation? What will be the phenotype(s) of the offspring resulting from a cross of an F1 individual back to its rough parent? What will be the phenotype(s) of the offspring of a cross of an F1 individual back to its smooth parent?
Suppose that you are tending a mouse colony at a genetic research institute, and one day you discover a mouse with twisted ears. You breed this mouse with twisted ears and find that the trait is inherited. Both male and female mice may have twisted ears, but when you cross a twisted-eared male with a normal-eared female, you obtain results that differ from those obtained when you cross a twisted-eared female with a normal-eared male: the reciprocal crosses give different results. Describe how you would determine whether this trait results from a sexlinked gene, a sex-influenced gene, genetic maternal effect, a cytoplasmically inherited gene, or genomic imprinting. What crosses would you conduct, and what results would be expected with these different types of inheritance?
The long hair of Persian cats is recessive to the short hair of Siamese cats, but the black coat color of Persians is dominant to the brown-and-tan coat color of Siamese. Make up appropriate symbols for the alleles of these two unlinked loci. If a pure black, long-haired Persian is mated to a pure brown-and-tan, short-haired Siamese, what will be the appearance of the F1 offspring? If two of these F1 cats are mated, what is the chance that a long-haired, brown-andtan cat will be produced in the F2 generation? (Use the shortcut probability method to obtain your answer; then check it with a Punnett square.)

In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype If you carried out this test cross, what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation?
If two gene pairs A and a and B and b are assorting independently with A dominant to a and B dominant to b, what is the probability of obtaining: a. an AB gamete from an AaBb individual? b. an AABB zygote from an AaBb x AaBb cross? c. an aaBb offspring from an AaBB x aabb cross? d. a phenotype aB from an Aabb x aaBb cross? e. an ab gamete from an aaBB individual?
Two recessive traits in mice—droopy ears and flaky tail—arecaused by genes that are located 6 mu apart on the same chromosome.A true-breeding mouse with normal ears (De) and a flaky tail ( ft)was crossed to a true-breeding mouse with droopy ears (de) and anormal tail (Ft). The F1 offspring were then crossed to mice withdroopy ears and flaky tails. If this testcross produced 100 offspring,what is the expected outcome of phenotypes?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream-colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited? _______________ Identify the genotype of the white guinea pig. ________ Identify the genotype of the yellow guinea pig. ________ Identify the genotype of the cream-colored guinea pig. ________ Identify the genotypes and the corresponding phenotypes of the F2 progeny. Give the genotypic ratio. __________________ Give the phenotypic ratio. ___________________
You perform a cross between two true-breeding strains of zucchini, One has green fruit and the other has yellow fruit. The F1 plants are all green, but when these are crossed, the F2 plants consist of 9 green: 7 yellow. A. Assuming that wild-type zucchini are green, how would you describe the phenomenon that occurred in the F1 of part (e) of the parents and progeny?.
In pigs, let’s assume that a straight tail (T) is dominant to a curly tail (t). Let us also assume that brown color (B) is dominant to spotted color (b). Find the phenotypic ratio of the offspring of each for each of the three crosses below. In order to receive credit, you must show your work. TTbb x Ttbb Ttbb x TtBb TtBB x ttBb
On a fox ranch in Scandinavia, a mutation arose that yielded a “platinum” coat color. The platinum color proved very popular in the fox coat trade, but, in spite of enormous effort on the part of fox breeders, a pure- breeding platinum strain was never achieved. Every time that two platinum fox were crossed, some wild-type offspring appeared in the progeny. For example, the repeated crosses of a single pair of platinum fox produced 83 platinum and 38 wild-type progeny. All other such crosses gave similar progeny ratios. State the genetic hypothesis that accounts for these results.
In a population of rabbits, you find three differentcoat color phenotypes: chinchilla (C), himalaya (H),and albino (A). To understand the inheritance of coatcolors, you cross individual rabbits with each otherand note the results in the following table.Cross number Parental phenotypes Phenotypes of progeny1 H × H 3/4 H : 1/4 A2 H × A 1/2 H : 1/2 A3 C × C 3/4 C : 1/4 H4 C × H all C5 C × C 3/4 C : 1/4 A6 H × A all H7 C × A 1/2 C : 1/2 A8 A × A all A9 C × H 1/2 C : 1/2 H10 C × H 1/2 C : 1/4 H : 1/4 Aa. What can you conclude about the inheritance ofcoat color in this population of rabbits?b. Ascribe genotypes to the parents in each of the10 crosses.c. What kinds of progeny would you expect, and inwhat proportions, if you crossed the chinchilla parents in crosses 9 and 10?
