A researcher at ASU is studying the exotic Unicorn Fairy plant. The plant has three genes of interest with the dominant alleles being T-tall, H=hairy leaves and P=purple flowers. The three genes are located in different chromosomes. A trihybrid plant is crossed with a plant that is heterozygous for T and homozygous recessive for the other two genes. What is the probability of getting offspring that is tall, has hairy leaves and white flowers? 9/64 5/8 8/64 O 3/64 O 3/16
4. In celery the leaves can be curly (Dominant; L) or straight (recessive; l). Another trait is spots on the leaves. Dark green spots (G) are dominant over white spots (g). Create a Punnett square that shows all of the possible offspring that could occur from breeding the following: 1. Plant 1: Heterozygous dominant for both traits 2. Plant 2: Recessive for both traits 3. Include the percentage/ratio of occurrence for each phenoty
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?
5. Flower color in snapdragons is inherited in an incompletely dominant manner. Assume that RR = red flowers, Rr = pink flowers, and rr = white flowers. What would be the genotype and phenotype ratios of the offspring of two plants with pink flowers?
5. If flower color shows codominance, and R = red and r = white, what will the %3D %3D offspring of a cross between RR x rr look like? * 100% red 75% red, 25% white 100% red and white 100% pink 25% red, 50% red and white, 25% white
2. In terms of pea plant height, tall plants (T) are dominant over dwarf plants (t). Purple flowers (P) are dominant over white flowers (p). Create a Punnett square that shows all of the possible offspring that could occur from breeding the following: a.) Plant 1: Heterozygous dominant for plant height, homozygous dominant for flower color b.) Plant 2: Heterozygous dominant for plant height, homozygous recessive for flower color c.) Include the percentage/ratio of occurrence for each phenotype.
