1. The height of a wheat plant is determined by several genes. In a variety the minimum size is 12 inches and the maximum is 24 inches. 12-inch plants were crossed with 18-inch plants, and produced an 18-inch F1. The F1 was allowed to cross each other, and an F2 was obtained in which the 12 and 24 inch plants were obtained with a frequency of 2/8195. How many genes are involved in determining plant size in this variety of wheat? Select one: a. 5b. 6c. 4d. 3

A heterozygous tall yellow plant is crossed with a homozygous short green. What will be the genotypes 3. and phenotypes, and probabilities of the first generation? Genotype of the heterozygous tall, yellow plant Genotype of the homozygous short, green plant Genotypes Phenotypes Right handedness (R) is dominant over left (r) Browyn eves (B) are dominant over blue (b). A man who is blue eyed and right handed, whose father was left handed, married a left handed woman with brown eyes, whose mother was blue eyed. What are the possible phenotypes and genotypes of the offspring and the probability for each? 4. Genotype of the man Genotype of the woman Genotypes Phenotypes What is the probability of getting right handed offspring? What is the probability of getting blue eyed offspring? What is the probability of getting offspring heterozygous for both traits? What is the probability of getting offspring that are homozygous dominant?

States) B *In nature, individual plants of Plectritis congesta bear either winged or wingless fruits. Three individual plants were collected from nature (thus not necessarily pure breeding) before flow- ering and were either crossed or self-pollinated. The results are shown below. Number of progeny plants Wingless 0 30 80 0 31 Cross 1 2 3 4 TU Parental phenotypes Winged #1 (selfed) Winged #/2 (selfed) Wingless #1 (selfed) Winged #1 X Wingless #1 Winged #2 X Wingless #1 Winged #1 X Winged #2 The fruits of two different forms of Plectritis congesta, the sea blush: Wingless fruit and winged fruit. a) Give a concise genetic hypothesis for the inheritance of fruit shape as determined from these crosses (include the number of genes, number of alleles, and dominance relation- ship between alleles).² b) Give the most probable genotypes of: (define your alleles) 2 Winged #1 Winged #2 Wingless #1 1) 2) c) If you self-pollinate the winged #2 plant and planted six seed, what is the probability of…
