In horses, there are four alleles at the A locus. Arranged in dominance sequence, they are A (wild), gb (bay), a (brown), (black) If you bred several bay mares whose sires were brown to a brown stallion whose sire was black, what are the genotypes of the parents; what type of offspring would be produced; and in what proportion? O a Aab x a ad; all wild O b. gdab x a°ad; all black O C. gaad x a°ad, 1/2 brown, 1/2 black O d. Aab x acad; 1/2 bay, 1/2 wild O e. abac x acad; 1/2 bay, 1/2 brown

Pea plants have pods that are smooth (inflated) or constricted in shape and green or yellow incolor. These two autosomal traits observe the laws of Mendelian inheritance and assortindependently of one another. One gene affects pod shape and one gene affects pod color. Theallele for the smooth shape of pods (I) is dominant over the allele for the constricted shape ofpods (i) and the allele for the green color of pods (G) is dominant over the allele for the yellowcolor of pods (g).A pure breeding female parental pea plant with smooth green pods is cross-fertilized with a purebreeding parental male pea plant with constricted yellow pods. The resulting F1 generationplants are then self-fertilized and F2 generation progeny are obtained.The distribution of the appearance or phenotypes of the pods of the F2 generation plants are______.a- 100% smooth green podsb- 100% constricted yellow podsc- 50% smooth green pods, 50% constricted yellow pods, 0% smooth yellow pods, 0%constricted green podsd-…
In roses, purple flower color is determined by the dominant P allele, while pp homozygotes are white. The presence of long stems is determined by the dominant S allele, while ss homozygotes have short stems. Both mutations are completely penetrant. A test cross was performed between a rose plant of unknown genotype with a white flowered, short stemmed rose plant (pp ss) and the following 200 progeny plants were obtained: 84 white flowers, long stems 16 purple flowers, long stems 82 purple flowers, short stems 18 white flowers, short stems Select the statements below that are TRUE. Select 2 correct answer(s) The P and S genes independently assort during meiosis. The map distance between P and S is 17 CM. The genotype of the progeny plants with purple flowers and short stems is PP ss. The map distance between P and S is 83 CM. The homologs in the plant with unknown genotype are p S and Ps. The homologs in the plant with unknown genotype are PS and p s.
In horses, assume that there are three colors affecting genes with the following effects: AA is lethal, Aa is white (albino), and aa allows color. B_ is black and bb is chestnut. D_ is solid and dd has white spots on color. (Albino would not show spots). A stallion that is heterozygous for all three genes and a mare of genotype AaBbdd are mated.a. What color is the mare and what are the genotypes of the gametes she produces?b. What is the color of the stallion and what are the genotypes of the gametes he produces?c. Construct a Punnett square and determine the frequencies of phenotypes that would be expected in the LIVE offspring.

In silk moths red eyes (r) and white banded wing (w) are recessive to normal eyes (R) and 10m.u. apar normal wings (W). A moth homozygous for red eyes and white banded wings is crossed with an individual who is homozygous normal for both traits. The F, progeny are testcrossed with the following progeny produced: Normal eyes, normal wings Red eyes, normal wings 19 Normal eyes, white banded wings Red eyes, white banded wings 426 a. What phenotypic proportions would be expected if the genes for red eyes and white banded wings were located on different chromosomes? b. What is the genetic distance between these two genes? 418 16
The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas plants with small leaves are P'P'. The trait for red flowers is controlled by the genes RR, pink by RR', and white by R'R'. A cross is made between two plants each with medium-sized leaves and pink flowers. If they produce 640 seedlings, what would be the expected phenotypes, and in what numbers would they be expected?
In kangaroos, pouched kangaroos (P) are dominant over pouchless kangaroos (p) and bushy tails (B) are dominant over skinny tails (b). You perform the following cross and observe the progeny. PPBb x Ppbb To determine if the difference between the observed and expected results are due to change, you perform a chi-squared analysis. What degree of freedom would you use for this analysis? 0 20000 2 AWN 3 4

A test cross between a plant of genotype PpSs and the tester white plant with wrinkled seed coat (ppss) gives the following numbers of progeny in four phenotypic types. 14:87:83:16 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat). a. What is the expected ratio of progeny phenotypes assuming independent assortment of alleles? b. Explain how ratios of progeny show that the two genes are linked. c. How many map units separate the purple and smooth genes? Show your calculations. d. What is the “parental” genotype of the heterozygous parent? (i.e. Which alleles of the P and S loci are present on each of the two chromosomes of the doubly heterozygous parent of this test cross?)
