- In giraffes, long neck is dominant to short neck. Long neck is denoted by the dominant allele, N, while short neck is denoted by a recessive allele, n. Write the genotype and phenotype for the following organisms: homozygous dominant organism, homozygous recessive organism, and heterozygous organism.A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower From the cross (P1) RrDdccOoHhWw x (P2) RrddCcooHhww, determine: Note: RrDdccOoHhWw is one genotype. a.

What is the probability of obtaining the RrDdccOohhww genotype in the progeny?e. What is the probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny?In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?

What is the frequency of the i allele?Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)?

- Consider a mating between two individuals represented by genotypes NnTT X NNTt. Uppercase letters represent dominant alleles and lowercase letters represent recessive alleles. Assume the N and T loci segregate independently (i.e., are not linked). What is the frequency of double heterozygotes (NnTt) in the offspring of these matings? Group of answer choices 1/2 1/16 1/8 1/4A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?) homozygous recessive, rr heterozygous, Rr homozygous dominant, RR In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?) Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR. Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr. Perform a test cross…Identify each of the following as an example of allele, genotype,and/or phenotype frequency:A.
